These wheels are very hard to find. The key is to find a wheel that has a 6" width and usually the backspacing will be OK. The wheels on the 1951 1 Ton are not hub piloted and in fact the front hubs are much smaller than the rears.
The newer wheels, 1999 and up or so, have a metric spacing on the studs, so I have been told.
Oh, Stockton Wheel will make up wheels for your particular backspacing. They can even take your old splitters and mount the centers in a new rim assembly.
