  1. Is the screw at the base of the distributor there supposed to be through the oval slot on the left?
  2. Here is the thermostat hose and line to the intake: bends back rather sharp but hose doesn't pinch
  3. Picked up the parts - rubber hose, steel line, and will be borrowing a line bender from a friend to make it tuck in nicely. Now I'm just having trouble with where on the intake it is actually supposed to route to. From the description and image above: ..."a hard line up to the intake by the vacuum fitting for the brake booster and another rubber hose to this fitting". I can see in datzenmike's reference pic that the modulator line ties in with the main vac line at the intake port closest to the driver's side. Mine already has a hose there that wraps all the way around to the vacuum assy-control on the distributor: Is this set up incorrectly? There are two additional ports on the intake that were entirely plugged up with some sort of debris or filler. I'm not sure if this was just settled dirt or if someone purposely packed it with filler in an attempt to block the ports, but it took some work to clear them out. Are one of these ports where the distributor vacuum hose should route, opening up the connector at the booster hose joint for the modulator line? I also found this guy hanging below the booster with no hoses connected to it, and the hose snapped right at the frame as soon as I moved it: Followed the line back underneath the truck and it led under the rear passenger fender above the fuel port. CarPartsManual labels this part as the "Flow Guide" and it appears to route to the air cleaner and carburetor, possibly more. Guessing most of this was yanked out when two owners back put a 32/36 carb in (an EMPI EPC), and it never got set back up with the most recent PO took that carb off in favor of a stock-style carb. I figured this flow guide and its lines don't have anything to do with the modulator line, but it does have to do with vacuum which is a total mess on my truck as a whole and I'm guessing its important to have connected. Any chance for a reference pic of someone's properly connected distributor line, as I'm guessing its improperly routed and that's why I'm having trouble figuring out where to connect the modulator line. And for that flow guide, is this part of the "optional" emissions components a lot of people delete, or is it actually crucial to having a well-running truck? My guess is that a lot of these reroutes and strange missing pieces and connections are all due to an attempted emissions delete and were set up for the EMPI carb. I have no preference as to which carb I use out of the two I have (EMPI EPC 32/36 - found video proof of the truck running with this carb on it in 2016, or a $90 ebay carb in the Hitachi style that the PO ordered and put on for some reason), so if it would make more sense to put the EMPI back on and only connect what is absolutely necessary, I'm all for that. And if its any help, I believe this is a 49 state truck, not a Cali.
  4. Thanks again Mike for the helpful information and images, as always! Time to get crafty
  5. Found the part number(s) for the Vacuum Modulator line on carpartsmanual, but can't find any hits online to order a replacement part. Plenty of hits for other 60's/70's vehicles, but not for Nissan/Datsun. Is this something I could just make out of brake line if I bend it correctly and connect it to the tube elbow? Doesn't look like there is enough demand for this part for it to be sold in the correct length and shape.
  6. Thanks datzenmike. I'll be ordering a line and modulator in the next few days. It has definitely been interesting seeing what goes missing on these older trucks, but I'm enjoying learning more about them from the community here!
  7. Hey everyone! After not posting for about a year, I'm finding myself working on the 620 a lot again recently, and as such, finding all kinds of new questions to ask. A buddy of mine who knows a lot more about vehicles than I do pointed out that my truck appears to be completely missing the vacuum modulator and vacuum line. I'm curious if there is any reason why a previous owner would have removed these parts, and how I was able to drive the truck home without it. I have the '73's 3-speed Auto Jatco 3N17B transmission with an L16. When I drove it home, it wasn't getting much power while climbing a hill and I later attributed that to the vehicle having no fuel and me not knowing it, but I'm guessing it could have also been that the carb wasn't tuned, that the missing vacuum modulator and line prevented it from downshifting, or possibly a combo of all 3 issues. Here is a quick snapshot of where it should be: So is this something I need to order and throw back on there, and is the fact that it is missing sensible to anyone? Thanks!

    Frontier rims

    '05 and later Nissans have the smaller PCD. '01-'04 stock rims seem to have the styling I like the most, and the correct PCD (and offset in many cases). America's tire sells Hankook Optimos for $200 a set in stock size. I'll probably be going with those once I clean up the slot mags. https://www.americastire.com/buy-tires/hankook-optimo-h724/p/10702 And turns out pick n pull doesn't even let you pull rims, at least in Sacramento. I called 3 locations, two said they recycle the stock rims and sell the specialty rims up front for a premium (not the prices advertised for rims on their website), one location didn't answer the phone all day. Called a Nissan dismantler as well and they said they sell the rims and would check their current inventory and let me know which vehicles had a set of 4. Never heard back. In the meantime I'm going to clean up the mags and snag those hankooks.

    Frontier rims

    Here is what I'm working with now. Set of four mags (14") in pretty good shape: Set of four of these (I'm guessing stock?)(14") in varying condition. Best one looks like this: Roughest looks like this (Bottom): Overall I guess they're not too bad? Might be able to bend the white one's lip back to shape.

    My stock rims are on the bent and bruised side unfortunately. I do have 14" slot mags, but long term I won't be able to stick with the 14's and have clearance for the beebani disc conversion I want to do. I agree with you though, going classic looks very nice!

    Just found this Xterra s/c ten minutes from work. Definitely going to see if the rims are still there tomorrow. Anyone running Xterra rims?

    Frontier rims

    I'm debating making the drive to Fresno over these rims (just shy of 3 hours) to throw on my '73 620. My brain says no but my heart says yes. Examples on a Datsun pickups here: https://ratsun.net/topic/35913-sunkist-521-ka24e/page/4/ They look incredible. So far they seem difficult to find on CL and are prohibitively expensive on eBay (~$160 each). I'll either get these or maybe 90's Pathfinder wheels (much more abundant near me, though much less attractive in my opinion) so I can do beebani's discs on the front at some point. Are there any more common 15"-17" rims the community likes with the correct offset/bore to just mount right up? I just got through the 24 pages in the truck tire thread and it looks like there are tons of options, but I'm not sure which need to be hacked up to fit properly. It sounds like pre 04 Xterra, frontier, and most early Pathfinders mount right up. Any other favorites? Thanks!
  13. Thank you for the info and resources! Turns out the black truck is a '73, which explains the L16. The previous owner mis-advertised it, but the registration history checks out.
  14. For Pathfinder wheels do you need to add spacers or will they mount as is?
  15. That makes a lot of sense. I'm planning on watching ChrisFix's drum brake walkthrough on YouTube before attacking it with any tools, because I'd likely have as successful an attempt as the former owner if I tried now. I've worked on brakes on my Corollas and Rav 4, but never drum brakes.
