Any rear from a Camaro or Firebird form 1982 to 2002 will bolt right in. The '93+ rears are a couple of inches wider, so using one of them would make your rear track width wider than the front. Some guys like that, some guys don't.

The '88 and older rears had crappy disc brakes...the '89+ brakes are better and the '98+ brakes are MUCH better (although you'll have to fab a bracket for the E-brake cable to use them.) They were all available with posi.

Some '85-89 cars had a 9-bolt rear, as compared to the 10-bolt they used in all the other cars (count the bolts on the diff. cover to tell between the two.) The 9-bolt is stronger, but harder to find parts for.

The older rears ('82-'86 or so) may have used a different thread pitch on the brake lines, which would have to be adapted to work.
