Can anyone help me with what should be the correct outside handles for this truck. I know what the hand grab part looks like, but the inside length is what is confusing. I have seen several sizes ranging from the short portion being 1-1/4" to 2-1/2" and the small square shank from 3/8" to 1" long. Did this truck have a locking door handle on it? I know the '38 had a lock only on the passenger side. Thoughts appreciated. Tom
