The answer depends on the specific part. However the years 1982 to 1992 are called 'third-gen' in f-body cars and many parts will interchange across the entire series.
ya
1993-1997
will a 3.8 engine from a2002 Camaro interchange with a1999 camaro
No. Call a wrecking yard. They have interchange books that will give you the exact years, but, off my head, I think 82, to 91?
Yes.
yes it will camaro parts from 82-92 will interchange
1994-2001
Yes. They are the same, except for horsepower ratings.
All Camaro and Firebird/Trans Am T-Tops from 93-02 will interchange.
1982-1992
Yes
should be 93-97 camaro. i don't believe firebird/trans ams will work
