S13 Rear Cradle Into A R32 Gtst

[tiels32]

I've got an s13 rear cradle to put into my r32 gtst. The main reason for doing this is there is movement in the tie rod and movement on the inside of my rear steering arms where they go into the hicas lock bar resulting in quite abit of movement of the rear wheel even by hand (outer traction rod bushes stuffed to). The 2-way diff I've had a short time definetly doesnt agree with it. I wanna get rid of the hicas lock bar and put in some proper adjustable arms. I've been told I need to use s13 rear uprights (wheel assembly) and bolt my 5 stud hubs and disc onto them. I've heard the s13 has a different lower ball joint? Is this correct. Everything else is the same I'm lead to believe. If everything else fits is it possible to just bolt the r32 lower control arm onto the s13 cradle. I've got the chance to purchase some adjustable rear lower control arms from an r32. Will these fit the s13 rear cradle? Any advice would by great! I just wanna get everything organised so the swap over can happen in one good session, not over a couple week period chasing up parts.
