I bought a Dana 60 rear end from a Dodge 1 ton, narrowed it to 56 inches wms to wms put my own custom disk brakes on it, changed the bearings and rebuilt the Power-loc diff. I changed the whole axle to a semifloating axle setup with new Mopar outer bearing housings and bought 35 spline fred williams axles for it all for $640.00
I know that MVs are more expensive for parts, but if I can make it, I wont buy it. I saw annother site that showed how that kit went on also and the guy said it cost him almost 900 bucks when he was finished with it because of the calipers and core charge and inner bearing seals.
It seems to me that if a new ring is welded to the hub to mount the rotor to, make a caliper bracket, and modify a ford rotor, that should be it. The biggest problem I see is the caliper brackets ears that hold the caliper on look complicated to make.
I like the look of the original axles so I won't be changing them. I know it would be easier to swap them out to get disk brakes and a normal wheel pattern. I have certain rules when I build a Jeep, like no chevy 350s allowed. not that I dont like the chevy 350, but EVERYONE and their brother puts a 350 in Jeeps. Its annoying, Its a symphony of sameness.
I drive what I drive because its different. I think members of the Zone are creative to say the least and try to make the BEST modifications not just the easiest ones to do.
