81' through 84' should be all the same. also, 280zx struts of the same years should fit on our 1st gens... the 81' through 84' is mostly based on the s30 chassis, same as the 280zx. all the parts you'll need are fairly easy to come by online, just google it, ebay has some stuff for z cars from time to time I'd also recommend a little research on the hybridz forum or other z car forum, very informational and helpful, maybe some member's classifieds would catch your eye... I just bought a set of front & back struts, rear sway bar, wheel bearings, full urethane bushing set, tierods, endlinks and front lowering springs for 280zx. most of the parts were pretty reasonable, I got all this so far for a little over $400. I just haven't got around to installing any of this, I'm still needing front control arms and ball joints, once I get those, I wanna install it all in one shot.
I'd recommend this site for a few part #s and a little advice from a guy that seems to have built a few modded 1st gens! I'm not sure, but I think this guy was/is on the org as well :
