This is a pair of original Foxcraft fender skirts that I have not been able to find a number on.  These may be Chevrolet, Pontiac, Oldsmobile, Ford, Mercury.  These are 41" along the bottom and 10" tall (with rubber seal).  These are in very good condition with light surface rust and the rubber seal will need to be reattached as seen in the photo. If you happen to know what these fit, I would appreciate an email.   Buyer to pay shipping according to the postal calculator.
