This is my 1958 3800 1 ton dually picked it up in a trade it has the 235 6 cylinder with four speed there is only a quarter sized rest spot in the floor and that's it other than that this cab is completely rust free. I couldn't believe there was still paint on the floor it is amazing I do have to replace the front fenders or fix them one of the other. If anyone else is reading this I am wondering if the newer 17 inch wheels will fit on my truck? My plans are just to keep it and enjoy it. The truck did set in a field for the last 22 years before I got a hold of it top end of the motor has been rebuilt and she runs like a top.
