The Stovebolt Site Forums The Shop Area Driveline Help Identifying Rearend in 51 3100

I'm replacing brake parts in my 51 chevy truck.I want to start with all new parts,shoes,wheel cylinders,hoses.I had the drums sandblasted and resurfaced.I ordered new shoes,wheel cylinders and parking brake cables. I noticed I had 2" shoes in the rear and LMC sent me 1 3/4" for it.That I assumed was due to the fact someone just put in the wrong shoes. Then I tried to replace the parking brake cables. One side was missing some parts and the other had been altered. I brought the new cables to the truck and found that they won't work. The style of attachment is wrong.The new cables have flanges that sandwich the backing plate.My backing plate has a recess built in with just a round hole for the cable.The existing cable is held in with fingers that are forced into the hole and then spread out when fully inserted.
It just dawned on me that my rear end must have come out of another model of vehicle. Looking at the manual I see that my differential should have a removable carrier with bolts toward the front. This one has a rear cover with twelve bolts holding it in.
What puzzles me is that the drums front and rear appear identical.The wheel cylinders they sent me fit like they belong there.
How can I find out what I have here?---Jack

Jack, it would be really helpful for everyone here if you could take a few pictures of the rear end. We have some amazingly knowledgeable people on this forum that can identify exactly what you have! A 12 bolt rear end is NOT what came with the truck. But you know that already!

Is the driveshaft enclosed in a torque tube?

No tube and I will get a few pictures tomorrow.

Here are locations/codes for 1951 Chevrolet truck rear end/axle.

I may not be much help on this one. I have one that looks just like it in my shop, and I THINK its from 62-68 1/2 ton, but I am not sure at all. It could be ME asking.
