Yes, but the magical diff he needs (or wants) is a gen 2 3.0 4.88 diff WITH LSD. Probably not going to find it, very rare if not non existant in the US.

Install locking diff (entire assembly) from a later 95/96 SR and call it a day.

OR:

Do some research on the "thrust block" and install LSD out of gen 1 V6... <img src="/forums/images/graemlins/kewl.gif" alt="" />
