This is the 82-87 Camaro or Firebird Body Side Molding New, available in white or black, both styles are paintable. This runs down the side of the car to prevent door dings and such. This is a small thin style (about 1/2") which is similar to the 82-87 (early 87). The 82-87 style comes in one roll section that has to be cut to fit for both sides.
The early style with the metal frame is not available.
