From my experiences as a warranty claim inspector, I'd reccomend staying as far away from that Explorer independent rear end as possible. Any repair work on that system takes a deep pocket and a bunch of dedicated tools. The rear hubs and suspension system would be difficult to adapt to a stovebolt frame, also.
