Hi John, I needed the same clips for my 53 Chrysler. Fasteners Plus has them on E-Bay, they have them listed under 50-54 Plymouth moulding clips but I looked in the Yellow Pages and found a local supplier. They are 5/8" by 2 and 3/16" which you can cut and bend to fit. Order extra because you will probably ruin some due to trial and error. They also worked for the rear window. Regards, Bill.
