Ha Rolling Dices, I looked at a 51 truck last week and the lower door seal, the one that is held on by the metal retainer, is a different profile than the glue on that was on the rest of the door. The seal on this old truck was the original rubber for sure.
As said previously the 47-49s have different cab and door seals that the 50+.
I agree, a picture of a finish door could really help. But your lower door windlace rubber seal, the one secured by the metal reainer, will be different from mine.
