silentcry1 Posted January 19, 2016 Report Share Posted January 19, 2016 I have a 1970 Datsun 521. I want to change my front suspension, that includes the brake. I wanted to know if you know of a swap. I have very old front suspension that I think I cannot use. Please let me know where and what are the steps to upgrading my front suspension. I have a Datsun 240 Z engine in it. Please let me know. Thank you. 1 Quote Link to comment
datzenmike Posted January 19, 2016 Report Share Posted January 19, 2016 You sure? The 240Z was a 6 cylinder engine. Front suspension. Cut the front frame from a '78-'79 620 and weld it on. Has disc brakes and ball joint suspension. Brakes can be up graded even more. Really need more information... what's wrong with the 521 front end??? 1 Quote Link to comment

flatcat19 Posted January 19, 2016 Report Share Posted January 19, 2016 You could try super glue if your welding skills are not up to snuff. I don't think Nissan's designers added provisions to the 70MY trucks to bolt on 79-later front ends. 2 Quote Link to comment
datzenmike Posted January 19, 2016 Report Share Posted January 19, 2016 Cut the frames under the cab. Weld the '78/'79 front onto the 521. Better yet get a late 720 and bolt your 521 cab and box onto that frame. You get the ball joint suspension and latre larger front 720 calipers and vented rotors. 1 Quote Link to comment

Or do as I am doing, i put a 1980 720 chassis under my 520. I am now in the process of putting Belltech 2005 lowering spindles on my 1980 720 chassis. this will lower the front 2" and also puts the later model 720 vented rotors and larger caliper. The link to my build thread is below in my signature. Quote Link to comment

silentcry1 Posted January 21, 2016 Author Report Share Posted January 21, 2016 Sorry I have a 1970 521 Datsun truck. I have a 200SX Z engine with the 5 speed. I really do not want to cut from another truck and weld it to mine. Im need to this. I know how to rebuild an engine but all else not so good. If you have step by step for another up grade that would be good. The reason I want to rebuild my suspencion or upgrde (might as well) the truck was stolen and returned to be suspencion damage. So I prefer to upgrade or fix the original but I do not know were to get parts. I had the truck park for 4 years. I love the truck. 1 Quote Link to comment

Shocks you can buy just about anywhere. Sway bars doesn't wear out but the bushings on the links connecting it to the LCA can rot away. The rubber parts are replaceable. Only thing left on the front suspension is the upper lower control arm bushings. 2 Quote Link to comment
Charlie69 Posted January 22, 2016 Report Share Posted January 22, 2016 I put a Z20 and a 5speed in my 70 521 back in the early 80s. Ran great! We need pictures! 1 Quote Link to comment

silentcry1 Posted January 22, 2016 Author Report Share Posted January 22, 2016 I would never put my truck in the yard. I want yo fix it and maybe let my son use it whe he turns 18 he gots 5 more years. Lol I went to the junk yard today and found a 1973 suspension from a nissan truck will this fit my 1970 datsun truck? This is what happen to the truck. When the truck got stolen they destroyed my spokes rims and the ran it with out a rim, so the suspencion scraped the floor destroying my suspencion. They ran it hard. When the police gave it back to me there was oil all over the engine, it turns on but there is noise in the engine, so im planning on rebuilding the engine my self.so since i was putting money in to it. I wanted to see if i rebuild the suspencion or upgrade it... no im not made of money but i love old cars so I really, want to repair it and make it look good. So any suggestions would be great, and if upgrade to disk breaks even better. Im in San Diego. Thanks. 1 Quote Link to comment

Charlie69 Posted January 23, 2016 Report Share Posted January 23, 2016 We love pictures. Wayno has done 3 trucks 2 521s and a 520 with the 720 chassis. It all depends on your skill level, appropriate tools' and most important a place to do it. Quote Link to comment
