Re: my 93 z died
Sucks to hear the car was ruined!
The Headers will not fit without serious modification. The Catback however will fit with minor modifications. Ive got a LT1 F-body Magnaflow system in my '89 iroc-z.
The rear differential will bolt in perfectly, however its 2" wider on each side, meaning you need to run 4th gen wheels.
Your best bet is to put as much as the harness as you can into the thirdgen
