I just had my parking lights out to clean the gaskets on my 2002. The part number from the left side is GM 16501927 CR4. I know the reverse light lens are from a Nissan, but by the part number for the front I assume tey are a General Motors application. Of couse, we should NEVER assume anything on an Avanti!!
