    The Official SWDP 11th Annual Barbecue August 18th 2018

    This is not mine and I have no stake in it whatsoever. But I've found Glas-Tex GT Spoiler camper shells made in Norco CA are extremely rare, even here in So Cal. Thought I should post it here for all the out-of-town/state Fontana-style and SDWP truckers? https://sandiego.craigslist.org/esd/pts/d/mitsubishi-truck-camper-shell/6655772402.html

    could also be the linkage bar that clips into a plastic retainer or you might a nut that fell off, or you might find two 1979 pennies rattling around like I did. but i’m with on this, take it apart and see what it is before you guess and blindly buy parts, it won’t keep you from driving it if the door panel is off

    620 A/C compressor mount

    Here is a bolt-on AC compressor answer for all you sweaty 620 owners! If you want to install a modern rotary Sanden compressor system in your Datsun 620 L20B AC system... Good news! They are still being made today, available from various AC supply sources and in various configurations. The hard part is finding a bolt-on bracket to mount it to your engine. I networked around with my old automotive AC suppliers. One found this schematic in his treasured old AC parts catalog upstairs after all these years in their modern AC shop attic. This is an ARA Air Conditioning aftermarket engine compartment schematic from the 70's showing everything their engine kit came with. It was made in the good ol' U.S.A. with plate steel compressor brackets, and barbed hose fittings and hose clamps to seal the hoses to the fittings. These hose ends typically leaked and were problematic, and made a tidy profit for the dealer's AC installation/ repair shop! lmao The evaporator (inside the vehicle AC unit) was a separate "knee-knocker" unit that hung under the dash. It has "Datsun" in raised sliver lettering on the "On/Off switch plate similar to the gauge bezel trim...giving it the impression it was made my Nissan. It was not made by Datsun / Nissan. This is a typical after-market AC unit. There were a number of manufacturers who made these. One even put the rotary compressor on the passenger side, but they were not in business long and is very rare. Have yet to fine one myself for a template to reproduce. All the aftermarket automotive AC manufacturers including ARA are out of business &/or no longer produce these units. In junk yards I've taken a number of these units apart that were already broken to prove this. If you pull the switches out of the plastic knee-knocker housing you'll find they say "Made in USA." If you look at the squirrel cage fan units you'll see they say "Made in Ohio. I've heard 620 owners with AC brag their ARA or other after-market AC is "factory air." It is not. Factor 620 air was made by Nissan utilizing a York compressor and cast iron brackets, and the inside unit was inside the dash, not hanging below it. I've heard 620 owners with AC in their truck brag it was a "dealer option" which is an obscure and meaningless term today regarding Datsuns. "Back in the day" when I was a Datsun dealer employee... a true dealer option meant you could order a 5 speed trans in a car that typically came with a 4 speed. Or you could order something shipped from the Nissan factory that was original Datsun/Nissan equipped and have it installed on your vehicle state-side (in the USA). This typically never happened with 620 Datsuns and earlier Datsun models. Why? Because Datsuns were brand new competing in the US market in the late 60's and 70's, production was low. Datsuns only became seriously in demand by the public masses when the first fuel shortage happened. There were very few Datsuns being delivered to a dealer monthly in the 70's, and the dealers had to take what they could get. Datsun Dealers would do almost anything to sell cars as they were. Come talk to retired Datsun dealer George Goespel (sp?) at the next SWDP BBQ on Aug 18 in Fontana CA and ask him questions about being a Datsun Dealer. He's great to talk to. If I recall correctly from my last conversation at a BBQ he said they only received 20-30 new vehicles a month. If they didn't have the specific vehicle a customer wanted, they had to trade with other dealers to get the one car they needed to make a sale. He said he often had to trade a couple vehicles for another coupled vehicles to get the one he needed. Then he'd be stuck with an "ugly" unpopular colored vehicle his salesmen couldn't sell. He contracted with a local auto/body shop to repaint the cars buyers wanted in specific colors and the ugly brand new cars and trucks so his people could sell them! Back to "dealer options..." Datsun dealers in different cities would buy the slotted mag wheels made popular in those days by Indy car racing, and later the "Jackman" style white spoked rims from local speed shops. They would install them on a new car /truck and put them in their show rooms to help sell the new Datsun models. (I still see Jackman style rims for sale on CL and the seller is selling them as 'factory rims!" lol) Dealers would drill into brand new Datsun doors to install cheap aluminum side-molding, hang all kinds of mirrors from local parts stores, install oversized tires and rims, hang local aftermarket step-bumpers, and cut into brand new Dats roofs to install aluminum/plexigalss moon-roofs... and call them "dealer options." How do I know this? I was one of those guys paid to install them. Early Datsun 620 Dealer options were typically local parts house aftermarket parts (typically crappy,) not parts made in Japan, and NOT supplied from Datsun/Nissan. In later 80's years when new models came out and the various Datsun production lines ramped up the later Z's had lots of actual Nissan options one could order from the factory, or buy from dealers. But never for 620's.

    mini truck bbq

    Gene, You've manipulated my words around pretty severely... "you have no idea what i went thru while i was in the military with my 3 tours to Iraq " I didn't comment about what you went thru in the service. I am sorry if you're having adverse affects from it. "and the conditions i was in at the time." I respect you highly for serving, and by what you imply sounds like severe conditions. Thank you very much for your service. "i am sorry you feel that my statement about me as a veteran disgust you." I didn't say anything positive or negative about you being a veteran. You're an interesting Datsun truck guy with a mountain of parts and history. At ER you told me you were done with Datsuns and were selling every part and vehicle. I bought a bunch of stuff form you and referred a bunch of buyers to you that day. Thanks. I only know what you recently put me thru, and possibly others about this new event of yours. You called me complaining nobody at SWDP was posting details on Ratsun about the yearly SWDP BBQ. You even implied their group may no longer exist, which I dismissed. You tried to enroll me in your BBQ in the same location a week before theirs. I explained SWDP are probably just lagging in scheduling, and that your event would dilute their event's attendance, and that it would be pretty insulting to their group. At that time I further recommended you create another type of Datsun event at different location and in a different month. You tried to strengthen your position by telling me another Dat friend of mine was already onboard with this BBQ. But after calling my friend I learned you gave him the same impression.. that the SWDP no longer exists? Unsure of your motivations I wanted no part of it, and suggested you then cancel your BBQ and apologize to SWDP. After this I told you to I didn't want to discuss if further and said not to call or text me further about it. You have an off-putting manner of twisting the truth or a person's statements around to make them feel guilty or bad, in order for you to "be right." I don't trust that. And the behavior of repeatedly throwing your military service history in people's faces is what I find disgusting. Not you. Not your military history. There's a big difference.

    I am so sorry Charlie. I was at work and quickly posted between a lot of interruptions . I was so used to seeing the two of you together at the events for many years, In my haste I simply mixed up your names Getting old sucks. My bad. My post was meant for Gene. I corrected it.

    Gene, , I barely know you from the ER swap meet and the SWDP BBQ's, and I've heard you use this guilt-trip phrase a good number of times now... "as a veteran who have put his life on the line for your freedom." It's disgusts me how loosely you use it, for just any little thing, and especially now to justify having your own way, even if you were somehow wronged. I know vets from Vietnam to current day, and I don't know another vet who would make such shameful statements. I would truly like to believe it is due to your PTSD... As I suggested when you called me trying to enroll me in this idea of an alternate BBQ because SWDP didn't post their yearly event info on Ratsun early enough for you...There's still time to apologize to SWDP for having your own, and cancel this one. Who knows, they might forgive you and still welcome you. As I told you before, I won't be at this event and can't support it. Meanwhile it appears cricket are chirping here.

    Those stories you hear from previous Datsun people.

    If you dig the attention, that's cool. I used to use a cheap $ 40 car cover at work to hide my 67 Chevelle. It worked wonders to prevent walk-up lookie-loos !

    620 A/C compressor mount

    Now that the original Datsun factory AC system has been identified, it raises a lot of other questions/considerations for those wanting AC in their 620: How technical are my mechanical skills? Do I know the types of AC seals and differences between R12 and R134? Do I how to successfully re-seal/convert AC hoses and compressors? Do I know the differences in refrigerant oils and not to mix them? Can I vacuum down an AC system? Do I have the equip for it or can borrow it? Can I do this kind of upgrade in my driveway/garage with the tools I have? Am I a bolt-on guy, or do I have the skills (or know someone/or a shop) who can fabricate custom compressor brackets and hoses etc. Only you can answer these questions. If you still want to proceed, you'll also need to consider the following: Do you have any access to R12 Freon? If so you can use an older R12 AC unit. If not you will have to completely flush the old system out and convert it to R134. Do you know about these before rushing out and buying a new or used AC unit? R12 is easier to re-seal and keep in the system, but it is also going for $30-35 per lb on Craigs list. Not sure what a shop charges, most no longer stock it due to cost and certification. The typical 620 AC system uses 3 to 3 1/2 lbs = $105 to 125 for Freon, before leak checking! R134 is harder to keep in a used system. The entire AC system including evaporator will have to be first flushed, then resealed with R134 seals. The compressor will have to have ALL oil drained, as R12 oil and R134 oil is not compatible. Then it will need to be resealed. Do I simply want to be able to bolt everything together and use the York compressor (that everyone seems to hate like an Edsel) so I can have working AC now (and check its efficiency first, and possibly upgrade to a rotary compressor later?) You can do this, IF you currently have a complete AC system in your car, and can reseal your compressor, or find a rebuilt one. Do I want to fabricate a compressor bracket for a rotary compressor like Sanden (aftermarket,) Hitachi (Nissan used these in most their other lines of vehicles,) or upgrade to another brand (ie: Honda, etc.) Then you could mate an old Evaporator (inside the car unit) with a modern compressor system. Vintage Air and other companies sell "ear" brackets that fit a Sanden compressor but they will still have to be welded to a plate to make a compressor mount. AND, it will have to be fitted to your block and aligned with a drive pulley. Some of these companies sell a flat plate already welded to these ears that is intended to bolt to a block or some other bracket. But it too will still have to be fitted to your engine block and aligned with the drive pulley. As of today, I have yet to find a modern company still in business who makes a bolt-on compressor bracket and idler pulley/ bracket that is a ready bolt-on installation for a 620. (If you find one please msg me!) You will have to weld one up yourself, or have someone make it for you, then address the drive belt and hose-end connectivity. That is the hard / expensive part, especially if you don't have those skills and/or equipment. I have seen posts suggesting using an original 720 mount bracket and compressor from 1981 and later 720 motors. That is NOT possible AND if it were... you would have to use a rotary Hitachi compressor. First: The bracket is cast iron and weighs about 10 lbs, and you can't weld on it unless you have some serious technical welding skills and materials. Second: The mounting tabs are also specific to a Hitachi compressor only. The mounting tabs are completely different from a York and a Sanden, these will not fit without serious adaptation, and would look horrible if so. Third: The bolt pattern to the L20B block is different from the 1981 and later engine block bolt pattern. If you have an existing Hitachi compressor and need a replacement, there is an outside chance Hitachi compressor maaaaaay still be available by aftermarket rebuilders on Ebay. But they will be extremely scarce if so. A super high-end technical AC shop may still be able to rebuild one. But, who is around who is that old and still has the specific knowledge about 40 year old compressors... that won't charge a fortune for it? I couldn't find one for the longest time in So Cal and had one hell of a time locating one for my stock 1980 200SX, and that was 2 years ago. I still haven't installed it and don't know if it is a reliable rebuild or not. Keep your fingers crossed for me! If you want to install any other compressor type like a Honda or some other brand, you'll have to conquer the same compressor mounting issues and hose-end fabrication listed above. Or you can buy a complete aftermarket modern "AC KIT" with and an under-dash evaporator unit, hoses, fittings, and a modern rotary compressor mount plate from a company like Vintage Air. BUT...you still have to conquer the compressor mounting issue. The last time I checked... Vintage Air and the other online companies DO NOT HAVE a ready-made bolt-on compressor mount solution. If they do now, please PM me! I would love to see it and buy one!

    620 A/C compressor mount

    Diagrams compliments of carpartsmanual.com The AC diagrams are in various places. Be sure to open the different ones and look for other pages. Sub pictures often show model or year variations, or other related components like the electric fuel pump (F) below. It did not come stock on most 620's only the ones with AC, campers, or other unique situations. It appears there was an early and late variation in this diagram. One would have to check the parts listing on the website to confirm this. Please note this diagram indicates a standard 7 blade clutch-type fan. This fan is the standard heavy duty clutch fan that came on the 620 L20b motors. Not sure about others it may have been on. It is NOT the heavy duty AC fan that actually came in the AC kits. This fan will be depicted in the next post diagram. If you go to Carpartsmanual.com and look at the individual parts listings below this diagram, you will see there are different part numbers for the different fans. There will also be a different pic of the 8 blade fan in one of the other diagrams. This diagram also shows the in-dash ducting and the backside of evaporator cover that goes in the passenger leg area, but this diagram does not show the center vents. Unfortunately, you have to move between the different diagrams to find all the variations of the AC parts. The factory AC fan had 8 shorter blades with more pitch vs. the standard 7 blade clutch fan with longer blades. Through junkyard prowling I have learned the 8 blade fan was also used on later model vehicles like the 1980 200SX with the EFI Z20 engine, and have matched them to my 620 AC fan. More pitch = more pulled air vs. trying to achieve the same by using more torque on a longer flatter fan blade. (But for all you minimalists who like to have manual fans and hidden wiring looms... at engine start-up, or with a hot motor sitting in freeway traffic... these fans do create lot of wind noise.) SAFETY TIP: Do not install AC and attempt to use a 4 blade manual (no clutch) fan with or without a fan shroud... you will overheat and seize your engine in short order! You may be able to get by with a 7 blade clutch fan and a shroud, but be sure to check the longer fan clearance with your shroud.There seem to be a number of different fan shrouds available from different vehicles. SAFETY TIP: If you are brave enough to install a new or used AC system on a used Datsun 620 engine with an old or original head gasket... Don't risk the life of your motor! You must ensure all components of the cooling system are in Excellent condition: Clutch fan is new or has great resistance when spun by hand (It should not spin a full revolution, if so replace it!) Thermostat is opening at 180 degrees Radiator is clean and not restricted Rad cap seals and works Cooling system has been flushed and runs clear Cooling system holds pressure - no leaks or seepages Freeze plugs look solid and are not crusty rusted or leaking (Don't forget the one on the back of the block between the engine block and trans!) There is the correct percentage of anti-freeze/coolant in system Heater control valve is not leaking Hoses are not soft, bloated, and are in good shape Oil change is fresh and regularly changed Fan shroud is whole, complete, and not cracked. (I've seen half-shrouds on newbs cars! Duct tape it if cracked!) Last, but not least... Ensure your temp gauge is working and accurate! Keep a religious eye on that gauge whenever using the AC, especially at low speeds or pulling a grade! If you maintain these, along with your AC system maintenance it will give you years of problem free cool to cold AC service. Remember this is 40 year old R12 evaporator technology. They did not perform like modern day evaporators. If you ignore maintaining the cooling system, you will kill your 35-40 year old motor very quickly. Stay cool!

    620 A/C compressor mount

    Datsun 620 engine bay orig AC diagram from the 79 Datsun/Nissan Factory Service manual NOTICE: This diagram depicts the real 8 blade AC fan for the large 5" bolt pattern clutch-water pump. It eliminates the mechanical fuel pump and replaces it with a block-off plate. An electric fuel pump is required back by the gas tank. It requires an extra drive pulley on the crank. It looks like the same pulley that is rubber mounted within a 720 harmonic balancer, but it would have to be cut, pressed out, or heated up with a torch to remove it to match up. Wouldn't be able to do that in a junk yard! There are two different cooling housings for different year ranges. You'd have to go to the website carpartsmanual.com to look at the parts listings to see what the different parts went to which year ranges. The front idler bracket/support compressor replaces the timing chain inspection cover. Front cooling hoses need some re-routing.
