parts interchanging

do parts on 1991 grand ams interchange with 1992 grand am

Body parts and interior parts are obviously not interchangable, Maybe some interior but only a few pieces, Under the hood engine parts should be interchangable for the most part since in the 3rd gen G/a's(92-95) they didn't start changing the enigine config until 93 so i 92 should be able to have some parts interchanged with a 91.. good luck
