wrong dana 30 and most are 2wd as its just a beam axle not worth the trouble if you going to go to the trouble of switching knuckles just do a wj swap...
I looked into this a little and read about untolerable ackerman angles from the resulting steering geometry. I don't know that I would recommend it or advise against it as I didn't collect enough information on the subject. You would, however, be able to run an inverted-T setup and have the equivalent of high steer.
