Zonargx Posted September 13, 2020 Author Report Share Posted September 13, 2020 (edited) Does anyone know how I can get all the bushings for a 1971 521 I need all the bushings even the leaf spring bushing. When I did the front disk conversion I was gonna replace them but the local auto parts seem to not have any information on them. So basically what I need is just the upper spindle and lower bushings and leaf spring bushings. Edited September 13, 2020 by Zonargx 1 Quote Link to comment
mrbigtanker Posted September 14, 2020 Report Share Posted September 14, 2020 Moog is all out of almost everything, due to the bullshit covid thing. I am in Los Angeles also. You will have to search for all of it. 1 Quote Link to comment

What lower bushing are you trying to find? The one pressed into the frame? I think I have the package for the rear leaf spring bushings in my garage... i can look for that later..... From autozone... Upper One in the frame Quote Link to comment
Crashtd420 Posted September 14, 2020 Report Share Posted September 14, 2020 I think these are the leaf spring bushings... They are listed for the 720, I know people swap the leafs onto the 521s so I think these are the ones but again I'd like to confirm it with the packaging in my garage ... Quote Link to comment
Greaser2 Posted September 14, 2020 Report Share Posted September 14, 2020 These pop up on EBay from time to time. 2 Quote Link to comment

mainer311 Posted September 17, 2020 Report Share Posted September 17, 2020 Very curious too. I’m fairly certain mine are completely shot. 1 Quote Link to comment
Charlie69 Posted September 17, 2020 Report Share Posted September 17, 2020 The shackle bolt diameter is larger on the 521 than the 720. Gene Knight was having a local spring shop custom make them for his 521. The rear spring shackles on a 521 are different from any other Datsun/Nissan trucks. 1 Quote Link to comment

I have an extra shackle and bolt for the leaf springs I'll do some measurements and maybe try to see if I can find the part number i used in my notes... i dont remember having issues with things fitting... This is why I said to verify, been a while since I installed mine.... 1 Quote Link to comment
Charlie69 Posted September 17, 2020 Report Share Posted September 17, 2020 The 521 leaf spring bushings used to be on eBay all the time. Now they show up once in a while. If I remember cxorrectly the 521 takes long and short bushings. 521 leaf spring bushings 1 Quote Link to comment
wayno Posted September 17, 2020 Report Share Posted September 17, 2020 (edited) Two types of 520/521 shackles Edited September 17, 2020 by wayno 2 Quote Link to comment
Charlie69 Posted September 17, 2020 Report Share Posted September 17, 2020 My 66 520 had straight shackles not the like the ones pictured above 1 Quote Link to comment
wayno Posted September 18, 2020 Report Share Posted September 18, 2020 Ones like in the photo I posted were on my 1971 Datsun 521 Charlie 2 Quote Link to comment
Zonargx Posted September 19, 2020 Author Report Share Posted September 19, 2020 Ok so the two small one are for upper Ans the long one is for lower. So for the leaf springs they change based off what type of shackles I have ? 1 Quote Link to comment
Zonargx Posted September 19, 2020 Author Report Share Posted September 19, 2020 My right side bushings are shot and I want to rejuvenate the ride. Am I gonna need a press to press some of this bushings in and out? 1 Quote Link to comment
mainer311 Posted September 20, 2020 Report Share Posted September 20, 2020 Shouldn’t need a press, but they could be pretty cruddy and stuck from rust. Should be able to pop them out with a punch and a hammer. 2 Quote Link to comment
datzenmike Posted September 20, 2020 Report Share Posted September 20, 2020 They rust and the rubber grips the rust. I've never had them come out without a LOT of work. 1 Quote Link to comment
gene knight Posted September 20, 2020 Report Share Posted September 20, 2020 (edited) charlie69: thanks for the shout out i do have a local shop who is making them for me and i switched my leaf springs to 720 nissan 4x4 leaf springs and i tried them on stock 521 leafs to compare the difference between 720 and 521 leaf eyelets. i can get the shop to make some more up if interested Edited September 20, 2020 by gene knight 1 Quote Link to comment
Zonargx Posted September 21, 2020 Author Report Share Posted September 21, 2020 I’m gonna wait till my schedule changes so I can start getting the bushings And replacing them. 1 Quote Link to comment
Zonargx Posted September 21, 2020 Author Report Share Posted September 21, 2020 After the disk brake conversion new bushing will make the truck feel smoother and also I’ll be putting in new shocks and possibly tires 1 Quote Link to comment
Charlie69 Posted September 22, 2020 Report Share Posted September 22, 2020 Just a suggestion, I have found that as old as these trucks are if you find a part you need buy it because it might be a while before the part shows up again. 2 Quote Link to comment
thisismatt Posted September 22, 2020 Report Share Posted September 22, 2020 Buy it? Buy 10. 1 Quote Link to comment
Zonargx Posted October 11, 2020 Author Report Share Posted October 11, 2020 (edited) So I want more hp on my truck and I found a ka24 from a 1990 240sx engine and transmission with the harness for $600. What would I need to get it running in the truck and what will I need to do to fit I in. I am assuming new driveshaft , fuel pump and mounts? I need all the advice so I can either take advantage of the deal on the motor or I’ll just go l20 with a 5 speed but I will also need help with what it’s needed to make it happen. trying to keep the swap on a budget Edited October 11, 2020 by Zonargx 1 Quote Link to comment
greenthumb Posted October 11, 2020 Report Share Posted October 11, 2020 You’ll need new mounts for engine, fab up a transmission mount, fuel supply mods of some kind to get the fuel pressure required for the EFI, radiator needs some monkeying or an upgrade to facilitate the new hose locations, gas pedal mods for the cable from the KA. IIRC the bell crank for the ebrake fouls on the downpipe, so something needs to be done there. I solved that one by using a cable from the 510 to avoid the bell crank altogether. The steering linkage from the pitman to the idler also interferes with the oil pan. Some guys just flip it, but I’m not a fan of the tapered joints sitting in nontapered holes if you do it that way. I chose to modify the pitman and idler to be able to mount the linkage from the bottom into the appropriately tapered holes. This is just my own experience, maybe others have different/better solutions. The l20b swap sounds like it’s a little less modification required 1 Quote Link to comment
