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.

I don't think they were talking about an independent rear, rather a solid axle out of the explorer, i to have the 8.8 with disc in mine with 3.73 gears, 700R4 and a 350 with a small cam. this combo works great, much better than the gm rear witch i have used in the past.
