Im writing here in desperation. I bought a 1954 Plymouth Belvedere 2dr HT about 4 years ago. Ive been working on it little by little over the years and have come to love the dog dish poverty cap that came with the car. The problem is only ONE came with the car!!! There are no markings or numbers on this particular and have never found another one like it. Ive posted a few times in different FB Plymouth/ Dodge/ Chrysler forums and have never received any info. The inside diameter measures about 8.5" and the outside measures about 9". Any info would be greatly appreciated.
