72 3/4 ton 4x4 rear drums Need HELP - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I originally posted this on the 4X4 board.

I need help trying to figure out the rear drums for a 72 3/4 4X4 for a guy I know. Here's what we know:

72 truck with 12" drums that have a 2" wide brake shoe face on the drum and the drums are about 5" deep in total. Upon trying to find new replacements he keeps coming up with a 12" drum for 2 1/2" wide or slightly larger shoe and they don't fit. It sounds like he may have an Eaton diff in it.

If anybody knows what we need to look for in the parts books to find the correct drums it would be greatly appreciated.
