They have minor differences, but they will interchange. For example, Firebird dash panels have separate platic speaker grilles, camaros just have slots in the pad. Also, in the center of a camaro pad on the front edge, there is like a 2.5" 'notch' in it. firebirds do not have this. These differences are hardly noticeable, its up to you if you mind them or not.
