The vast majority of the 1972's and 1973's came with the polyethylene valance but they broke very early in the ownership timespan. Some of them even broke while the cars were being driven onto the trailers at the assembly plant. It was a bad design, made out of never before used material, compounded by the mounting holes molded in the wrong place.

The original owner Rick, said the he had replaced the original poly valance with the earlier steel valance early on, when it cracked and shattered.

The poly valance has an upper cross bar that mounts against the underside of the nose and looks much more streamlined than the "gap-tooth" look of the replacement steel valance.
