Question abou the 1947 4 speed tranny

[Zach B]

About 3 years ago my dad and great uncle gave me this 47 chevy short bed that they had owned since before a was born. They had not touched the truck in all that time with the exeption of a seat. All the truck had was the frame, axles, transmission, the cab, and everything forward on the body. I'm wanting to go original with it but I have recently learned I may have a snag. I have yet to open the housing and see what kind of shape the gears are in but I'm worried about them being broken. If they are I don't know where I would go for replacement gears because of the fully unsyncronized part of it. Do any of you know where I would find a kit for it and still have a fully unsyncronized transmission if it does turn out to need repairs?
