What other car parts or models are compatible

Greetings, most all body parts interior and exterior 95 -99 are interchangeable. GM /Riviera made several engine compartment changes after the 95 model. The engine and engine parts 96-98 and some 99 model are interchangeable. But when you enter in the 99, (last year model), do your research, especially beneath the hood. Good luck..SEMPER FI

...and in addition, certain engine interchangeable components can be found in the Pontiac Bonneville ssei and other Buicks .
