Probably a given, but many of the rubber parts were leather during the war years.
Kip if you need a picture of the 41 rear window frame with screw attachment I can provide that. It may not be the best picture since its disassembled in the shed right now... I thought it was a 1940 thing, as my other 41 has the normal rubber seal????
Theres also a lot of differences between GMCs and Chevrolets of the same year and size.
