Looks to me like you have an AD bed for a 1 ton. The fender shadows and the split brace just behind fender center give it away. Also, the older trucks had a bed approx 4" narrower for the 1/2 and 3/4 ton than the 1 ton, 48-1/2" for the former as opposed to 52-7/16" for the 1 ton. The rear fenders for '46 and older 1 ton are different than for the AD. The older 1 ton bed had cutouts at the wheel with wood insert "liners" that jutted into the bed. Yours has no cutouts. The inside lengths were 1/2 ton - 78" inside, 3/4 ton 87" inside, 1 ton - 108-3/32" inside. I don't know how to attach a file to this or I'd add a pic of my 1 ton project.
