That was my first thought, too, Longbox. But weren't there some AD 3/4s that came with a box and duals? Didn't think that happened with TF trucks, though.
Starting in '56, you can get 6900 GVWR with either 17.5" DRW or 19.5" SRW. This was also the start of tubeless tires on one piece wheels. I believe 4.56 was the only choice on 3600s in both '56 and '57.
Edit: Just saw your "short box" signature, Dan. There's only one box available on a 3600, and it is the same as a 1/2 ton long box. FYI.
