Can I put early 90'seats out of a camaro n a 88 camaro

 

All 1982-2002 Camaro & Firebirds are a direct physical bolt in swap, no mods required. So yes.

The only issue you could run in to, is that is you try to put an electric seat in a car that never had any, or if you put 4th gen electric seats into a 3rd gen that had electric seats. The wires are there, but the plugs are different, so you hafta cut & splice.

BTW, a "search" would told you the same thing a hundred times over. The search feature here on TGO can be your biggest friend & gets you results to your questions a whole lot faster.
