As for the rear, 80CJ hit it on the head... late 70 and all early 71's came with offset 44's with flanged axles. earlier tapered 44's are just as strong, but have a 19 spline count, which will cut down your choices of traction diffs. While I don't know what your ultimate wheeling rig is, for mild most wheeling, a Powr-lok LS is a good choise and can be found in the 19 spline count. Just thought I'd shoot you an alternative.Good luck.
