Will - Are you around the Sonoita area? Those grasses definitely say S.E. AZ to me.
For anything pre second series 47 you are going to find it more difficult to find parts and mainly the ones regarding sheet metal, etc. Chev's of the 40's , Jim Carter, and various other sources will have some of the parts you are looking for. For original parts, you can find some overpriced ones on Ebay, but like all auctions, beware.
Good luck and welcome to the bolt!
