[crewguy]

Maybe I could answer some questions. 12-14 years ago after I bought my Stageway built 65 GMC crewcab, I was able to get in contact with the fellow who owned Stageway in the 60's. He told me they had two guys who built back doors from scratch. The doors are a lot heavier than the fronts. Cost for a conversion was $800 for the cab and $200 for the frame lengthening. I believe he said they got up to 32 units(trucks) a month at their peak. I've attached a couple shots of the back doors...you can see how they were pieced, and the cab construction.
