There it is!! 😎 I'm grabbing a couple of these, one to replace on my 521 & another as a spare to keep around!

I have looked at these trans tunnel plates (I have a 521, a 620 parts truck & a 1980 720 parts truck, all manual), the basic shape of that plate is the same, but they moved the shifter hole to suit the changes in transmissions over the years. I have all three plates, but will have to look again! Will post back here! I will eventually put the 77k original mile 1980 720 L20B & 5speed in my 521, but likely not until Winter sets in! 😁

If 5/8 hose (like 510), I have used a Dayco 80407 for the preformed 90deg on one end, then you end up with 2+ feet of 5/8 straight for another project! I just looked at my 521, looks like you need an "S" shaped hose, which you could buy qty 2 of Dayco 80407, use the 2 90deg preformed ends, use a connector in between to create an "S", but that's too many hose clamps for me! I would think that there is an "S" hose that somebody else might suggest! Following! I just read that you think the cyl head elbow vs the heater core tube are different sizes.........?? Ugh 😣 that complicates things!

Hmmmmmm interesting point 👍

Also can soak the whole fusebox in white vinegar for a few days, cleans the copper terminals up nicely!

FYI my original 1972 521 L16 dipstick is exactly the same as my 510 L16 dipsticks. I do not have any known 620 L16 dipsticks. When I pull a part, I usually write the application on it or on a tag (I'm an old parts guy by trade, so comes naturally!). I think the key is the fact that the L16 sumps are basically in the same "area" & I think all of the dipsticks were in the same spot...........the earliest change that I see is with the L20B & newer. Thoughts?

Every hub from various manufacturers could have a different "depth", even for the same application. Are you looking to rectify that gap or maybe you want a deeper hub to move whatever steering wheel you use closer to you or as far away as possible? I have seen thick spacers to push wheel closer to you, goes between the hub & wheel, but you need to identify the hub & wheel bolt patterns first.........there are at least 3-4 different bolt patterns ie Grant, Momo etc!

Correct! I had a USED hub & steering wheel from a 510, threw on my 521 to be able to move it. Yes, I have the same gap. I didn't look at t/s cancellation etc, but years ago I installed a Momo on my 1998 240SX. The hub kit was likely for an earlier 240SX WITHOUT an airbag, so it fit, but I had to lengthen the two pins on the backside that "cancelled" the turnsignals. They were simple "split pins", so found the correct diameter & length I needed at the hardware store & it worked great! I will pull the wheel/hub off my 521 & see if it is a similar situation....................I hate having to manually cancel the turnsignals! 😆

Those are normal factory welds...........😁

I might have a good USED fuse box. PM sent!

OK so for me it complicates, cuz I have a box of dipsticks...........only some are labeled like the 510 L16 (cuz that's what I started out with years ago!) & the L20B side stick (not the later front stick front sump). I will try to correlate with KELMO's part # application list, will let you know what I come up with! TJ Denver CO

I have lots of 510 L16 dipsticks...............might be the same? I have an original 1972 521 L16, but do not know if same as your 1973 620 L16...........?? That's three different L16 applications! I was just reading another thread last night regarding the oil pans being different, so the dipsticks might match the oil pan, which might mean the dipsticks are NOT the same.............?? Kelmo can you cross reference the 1972 510 L16 & the 1972 521 L16 dip stick part #'s, to see if the same?

Yes, but I'm pretty sure that the 78-79 510 A10 L20B was a FRONT SUMP oil pan. The oil dipstick was also relocated on the block.........pretty sure to the passenger side front. I've only had one front sump L series pan over the years & there are guys looking for them..........

Correct! 510 L16 oil pans are getting harder to find, but they MUST have the correct matching oil pick up tube to be the most valuable. I will not sell a 510 L16 oil pick up tube without the oil pan & vice versa............one without the other is much harder to sell. Just like with the trucks, the oil pan matches the chassis, not the engine........in other words you must have a 510 L16 oil pan & pick up tube to install an L20B in a 510 chassis! You must have a 521 oil pan & pick up to install an L20B in a 521 chassis. I have a 1972 521 with the L16 still in it, so I'm not sure that a pic would help here with it still in the chassis...........pans really need to be off & on the bench for the best pics. I will crawl under the truck (up on jack stands!) to take a look. I have 510 L16 pans & likely a 620 pan (but have no idea if early 620 or late 620). Let me know if you still need some info, but again, it's still in my truck, so I don't know how detailed I can be! TJ

Wow, this is a BAD year for fires! We are having a horrible fire season here in Colorado too! Been very dry, no rain, HOWEVER we got snow (in September!) yesterday & today, so hoping the fires will be under control soon.............once this storm is gone, it will quickly evaporate & we are back to dry again, back to more fire hazards! Thoughts & prayers for everyone! 🙏🙏🙏🙏

I would say that the bottom one is at least a 70-72 510 cuz has the same grooved pattern as the wiper & headlight knobs.......I just sold those to a guy. The top one is a plain knob, so my guess is early trucks..........I think my 1974 620 parts truck had a bigger one, so maybe before 1974...........??

Wonder if your brake junction block on the drivers side lower inner fender is gummed up inside, causing it to trigger the light? Did the car sit for a long period? That is where that red brake light is triggered if there is a failure. There is also a switch for that red light on the e/brake handle that can get oxidized............easy to clean! If the pedal has also gone soft, likely NOT the e/brake handle switch, but could be the junction block............??

Cool! Love your 620! Grew up as a car kid in the 70's, always loved the mini trucks!

Those chrome round bars were manufactured & sold by Amco, who also made rear trunk lid luggage racks, shift knobs & other cool accessories, from the 60's thru the early 80's. They made LOTS of Datsun products & marketed them thru the Datsun dealerships, so they were considered Datsun Dealer add on (not "factory") accessories. I worked at a British shop in MD in the mid 80's, we bought out one of their warehouses, sold LOTS of these products! 😎
