First of all i remember seeing a site somewhere that told you everything you need to correctly swap in the RX-7s rear end. But i ve been searching and i cant find it, so anyone who knows where this is that would help maybe answere some questions.

Secondly, all this coming up cause my brothers convertable 91 rx-7 is being ripped apart and i have first pick on parts but i dont know if its lsd? also i dont know what parts i need from it. help?

 

yeah, solomiata. I'm sure it's linked here somewhere.
Search solomiata and it might turn up.

I do not think any of the verts came with LSD. The only FC's that were LSD were the TII (won't work) and the GTU (leater, sunroof... loaded cars)

 

Here ya go:

Actually, the best posts you'll find on that subject are on M.net, much to most everyone's chagrin around here besides myself, it would seem.

I've done the swap and can post more later when I'm not on my way out the door.
