Depending on condition and conversion quality, could be a great deal. 5.3 Vortex? conversion. Those wheels would have to go though. http://knoxville.craigslist.org/ctd/5090982253.html
Seems like the fad is a Ford rear end so that makes sense. Kinda looks like a recycling yard. That swap is a simple one. It's just a GM with a simple computer box, plug and play. Son used an in line fuel pump on his truck. From what I see the body, glass, chrome looks nice!
The Explorer rear is a common tri-five GM swap and usually has disc brakes and is the correct width ...I learned this while doing research on which rear I was going to use in mine and was my #1 candidate until I found a GM 10 bolt for cheap.
I have heard un-good stories about this seller; he runs a junkyard in Montezuma, Georgia. I've never dealt with him personally, however. This would be the type deal you'd want to go over personally in detail before deciding, I would think. Pete
