Original plastic cover for rear defogger off a 1970-1972 GM A-body car. It is a black but can probably be repainted to whatever. All the studs are still there and there is no cracks on plastic. Hard to find these anymore without cracks. One of the studs is a little bent but it can be bent back into shape. I don't see any parts number on it but it does have some stampings on it as shown in pictures.
