1972 Duster fender splash shields

I used plastic on my cars. They keep pressure on the fender and do not hold the moisture , And they never rust, There was a reason they got away from the metal in 1973. And most of the 73 and newer cars didn't have as much rear fender well rust. The main reason I used them was to cut weight. I would use them on my Demon if I could find a set. Dusters are different and I only have Plastic for Duster not Dart at this time.
