Now that his car is back home from the paint shop, Aaron and I are replacing all the seals, gaskets, and weatherstripping on his '74 Dart Sport. I don't remember what the old seal looks like that separates the fuel filler neck from the body at the gas cap. Is it rubber or foam and about how thick? Anyone have a part number for the correct one?

Thanks,
Jerry
