I an just finishing up a 1953 6400. I ordered a lot of sheet metal, rubber gaskets, etc. from Chevs of the 40s and several other suppliers. Everything fit fine except for the floor panels. They were a litle too narrow for some reason, and I was forced to weld a small piece of sheet metal to join the two pieces where to toe board joined. I also ordered a new grille. I haven't installed it yet, but I have held it up in place, and it seems to fit. I don't think you will have any problem with sheet metal at all. Some of the mechanical parts may be harder because not many people bother with the big trucks, so the suppliers don't either. I had a hard time with some wheel bearings, brake seals, wheel cylinders, etc. I did find everything with the exception of rear brake cylinders. The rear end had been changed to one from an earlier truck, and I was forced to have those cylinders sleeved, which is expensive. Allen
