Won't need one Greg. Same 6 bolt pattern. 91 and up will be 23 spline, 90 and older will be 21 spline output. Will need a clocking ring for input shaft depth, but that's it.
Working on putting a little more power behind the Krawler, should be geared low and able to make wheel speed. Ok..anyone got a preference for clocking rings for this app?
The buggy justs need a few hours worth of wiring, I just haven't had the few hours.
Depending on the year of your aw4, you may need the 7/8" thick ring from Novak. That's what I'm using. They also have a flip version but my axles are passenger drop so I just used the adapter/clocking ring.
