Yota axles would be good. I'm either going that way or ford 9"/D44. Yota axles would be better though, then I wouldn't have to get new rims.

After I realised that the transfer case wouldn't fit I decided to fix my broken leaf spring at the back by replacing the center two leaves with the center two leaves from my dakota donor, and reusing the raider main and overload springs. The springs fit well, I only had to trim about an inch off the front of the second dakota leaf. When I got it all together I realised that I had lifted the rear about 2". Now she sits a little high in the back. Looks like I could clear 35's on the back for sure, maybe even 37's.
