Hi Steve,
Great truck you have there. I too have a 3800 series with a 9' bed from 1950. I live in the Twin Cities in Minnesota, too bad we couldn't have met up when you were here. A lot of the sheet metal is shared with the 1/2 and 3/4 ton trucks. Exclusive to the 1 ton are the bed sides, front bed panel, running boards, and running board aprons. Those parts are a bit harder to locate vs. the smaller trucks. Take good care of the brake drums - those are virtually non-existent for the 1 ton. Lots of parts are out there, just need to keep digging. Good luck with your work on it, and have fun with it. Tom
