I have done this swap: 8.8 explorer rear and used a dana 44 axle out of a wagoneer. I took the old style knuckles on the ends of the axle off. Then removed the ends off the d30 and with a little boring, welded them on the waggy 44. I then used the d30 outer stub/knuckle, etc. 2 detroits and 2 5.38 ring and pinions and I drove past everyone.
