        Parts like 3.55, 3.92, and SG are all potentially junk yard finds from Dakota trucks.

        I got my 3.55 R&P from a Jeep Cherokee. They used 8 1/4" rears too.

        Most late B bodies got 8.25s. If ordered with the HD suspension or towing packages, it would get the 9.25. (this is across ALL engines) Have had 2 77 400 4bbl doba's and they both had the 8.25.
