The rear valance. This is an extremely rust-prone area on the 70 to 73 Firebirds. No patch panels are available. This one is completely rust free, just dented in below the bumper line and in need of un-denting. The upper area is supposed to look this way ( the fiberglass tail panel and tail lights cover all of the area from quarter edge to quarter edge. The only visible part is the lower valance area with the dent puller holes in it.
