looking for inforamtion on swaping an Amc 20 into the rear of my 95 YJ, Got a front Dana 44 and a rear AMC 20 from a 1985 Grand Wagonner for next to nothing, and from all the asking I have done the 20 seems to be just as strong as the 44 so I want to keep it, but havent found any one who has done this before. Just have a few questions to ask
The original u-joints are the same on SJs and YJs, it should fit right on. The length of the model 20 pinion may be longer than the model 35, so it still may need to be shortened. Hope this helps, good luck!
