Not sure about the compatibility. Reading it sounds like some later models will bolt into the axle housing. The adjustment for the pinion is by shims between the bearing and housing. If you use an open drive line I don't how that will all work. The side to side adjustment is made by threaded bearing retainers. I put in the 3:55 ratio gears and that is why I did the work. Check your axles as mine had pits on them and I worked out a spacer that moved the bearings out to a good surface. Good Axles are impossible to find for these years.
