The rear valance was the original one to the car and I had a question about the fact that it will vibrate on the bottom of the gas tank and it seems I am missing a stiffener that goes from the lower bumper rail down to the bottom of the valance just inboard of the cutouts. Does anyone have a shot of what these look like on a 73 Here is a picture of a 70 car and this view came from my 73 shop manual but you look up parts and 70 is a unique installation.
