    Your easiest bet may be the flanged dana 44, 30 spline rear axle that came stock in the '69?-'71 CJ-5s and CJ-6s. This should be a near bolt in for what you have and a significant increase in strength. Hope this helps.

    could also get/make a full floating rear out of the current tapered axle.


    otherwise go easy on the loud pedal.

    It will be if it was from a pre-'72 CJ5. Your CJ2A has an offset rear axle to accomodate the Dana 18 transfer case, and in '72 (I think) AMC went to the Dana 20 transfer case which needed a centered differential.
