Did you ever measure the wheelbase on it? The 1-ton panel trucks were 133" and so were the 1 ton pickups with 9ft step side bed. 1 tons should have 8 leafs in the spring pack as well. C-20's were coil spring. Looks to be 1963 or newer since the front suspension is coil spring and not torsion bar.
If you can get the stamped code off the top of the rear axle third member that will help narrow down the year and maybe the application.
