84 200sx looking for advice!!!!

i have an 84 200sx. have had for 4 yrs. rebuilding. i broke a trailing arm. i couldn't find 1 so i went junking. ever since then i got alot of slop in the rearend. i cant find new ones or even bushings in my area. if any 1 can tell me who to call for parts it would be great. it has a rebuilt 2.0 just droper 2300.00 on tranny front end is all new except rack. wheels & tires this car ia awsome. just need help finding rearend parts. thanks

sorry i dont know anything about those cars but possibly they are interchangeable with other nissans of that era? i would look at a early 300zx, late 280zx, pickup truck, ect. otherwise google search for a 200sx only site

sorry i may be no help at all but...
