Thanks for the information guys. I knew it was rare. I had the pick between two - the other truck was a '57 Chevrolet 6400 with a late model sbc in it and a full complement of widowmakers. I think I made the right choice. I am probably just going to get it tidy'd up and get it running and sell it. I got it in a trade deal. I already have a much better '50 4100 Chevrolet that I am concentrating on. I just
wanted to rescue this old Jimmy.
