Hi all. Please help. I am rebuilding a 1950 Chevy pickup. My rear differential is leaking. I need to identify it so i can order gaskets. I don't see any identifying numbers. Attached are a few pictures. The differential has a torque tube.

Any help greatly appreciated.
Mike

With half of the pics showing the diff upside down, I was going crazy. But then again, it doesn't take much for that to happen. I think his rig is a 1/2T.
