While the 1997 and 1998 Chevy Camaros are very similar, there's no guarantee that the front bumper and headlights will be directly interchangeable. There *might* be minor differences in mounting points, electrical connectors, or even the overall shape that would prevent a perfect fit.
It's best to check part numbers for the specific bumpers and headlights from a reputable parts supplier to confirm compatibility. Even then, slight adjustments might be needed. Don't assume they'll be a perfect swap without verifying.
