George, on the gas cap issue for a 1955 Imperial, there are good used & NOS original gas caps out there you just have to find them. Call Lowell Howe, Bob Hoffmiester, Murry Park or others for used original caps. If no luck call the NOS suppliers found throughout Hemmings Motor News each month. A few months ago I bought a surprisingly good used gas cap for my 1955 C-69 from Lowell in California. If you don't have a copy of Hemmings pick one up from almost any place magazines are sold. Contact me privately if you need more help.
