Inner fender splash shields
Metal and plastic - if you look at the pictures in post 4 above, the Plymouth ones have a "pocket" molded in for the bolt that is Not on the edge of the piece. Dodge fender openings sweep back, while the Plymouth ones are straight up and down. The pocket moves the outside edge to that straight up and down position. Used on a Dart it would be out in the air instead of tucked behind the wheel opening lip. Here is a Dodge picture. If someone could post a Plymouth picture the mismatch would be obvious.
