Might sound like a dumb question, but what year range are the basic body shells of Ford's COE's the same, starting with 1948? Do they go 1948-54 like Chev pickup cabs? I found a nice '54 COE cab and front sheetmetal that's missing the passenger door and a very nice '48 door is listed here in the classifieds - will this door fit the cab I'm looking at? Steve
