Can you interchange a 97 Chevy blazer with a 2000 Chevy blazer?

Answer 1

A fair number of parts will be compatible. Some will not be - for example, if you want to put a 98+ front end on a 94 - 97 Blazer, you'll need the core support from a 98+ Blazer, Jimmy, Bravada, S10, or S15. If you have sealed beam headlights (most commonly seen on 2WD 94 - 97 models), you'll need the wiring harnesses for the lights, as well.
