The rear-end housing has two numbers cast into it, one on each half of the housing. They are 276661, with a C directly under it and 276662, with a D directly under it. There are 8 lug bolts in the wood spoke rims with 35 x 5 (8 ply) tires . There are 12 leafs in the leaf-springs on both sides.
All this sounds, and looks, like a huge rear-end for this truck. The rear of the truck is extremely high off the ground, especially compared to the front.
Any ideas as to what this rear-end is out of, or is it actually the right one for the '28 light delivery?
