That is correct. The '60-'62 Chevy's came with the Eaton HO32/33 differential. Personally I would go with a '63-'82 truck 12 bolt. No matter which differential you go with, you will have to either add, or relocate the trailing arm mounts. The mounts on the '60-'62's are farther apart than on the '63-'72's. The '63 & '64 12 bolt will have the same panhard bar mount, but the trailing arm mounts will need to be moved and likely an adjustable panhard bar. A '65-'70 12 bolt will need your original panhard bar mount transferred and the TA mounts moved. These will all be 6 lug unless you purchase aftermarket conversion axles. The '71-'82 12 bolts will be 1.5" wider and have the 5 x 5" wheel stud pattern. These will need both the panhard bar mount and TA mounts added. If you need a set of trailing arm mounts, I do make those.
