Mopar Rear End need help to identify

im doing a full convertion of the gearbox, driveshaft and rear end. i got a new made 833 OD 4 speed, and are currently making a new driveshaft.

That's definitely a 70's 8.25. (note the two ribs on the housing like your picture)
You would have to have the tubes shortened and get new axles plus move the spring perches before it will fit your car.
On the upside, Jeep Cherokee's and lots of other newer 4x4 vehicles have sure grip units that fit in those cases. (I know because I just did one)
Those same vehicles have gear sets in the 4.10, 3.55 and 3.73 range commonly and cheap.
THEN even the disc brakes from the Grand Cherokee or Liberty bolt right onto that rear end.
The carrier bearings are different between the newer Jeeps and these early 8.25's but they are easily sourced, and I have the part numbers for them from when I did mine.
I also had to get longer wheel studs because the rotors take up more of the stud than drums.

This is a 1973 8.25 Abody unit with Jeep Limited slip and 3.55 gears with Grand Cherokee disc brakes.
It's in my 73 Swinger right now and I'm really happy with it.
