I've got one.
HP non disco d30 4.56 complete disc to disc $300 (a new axle for the price of 2 new unit bearings...)
Fully rebuilt 10k miles ago no leaks (other than diff cover. RTV and 5 minutes to fix)
new discs, calipers, unit bearings, ball joint, u joints, axle seals, lug studs and 4.56 gears.
Lower control arm pockets have been boxed with 1/4" plate steel (skidplates),
Upper control arm pockets have been radiused in increased droop (added 4" of droop with a RE 4.5 lift),
The down side is there are no sway bar mounts. Drop in a locker and you're done
