Thanks for the info.
Yeah, I knew those FF rears were cool, I just wasn't sure what you could do with them.
I might could hook you up with some ifs calipers for a price on that dualie rear. 
I checked, they want $500 for the rearend. The place is pretty cool though, so if you pulled it yourself and talked nice, you might could get it for $350-400. They have 2 complete trucks, and they have all 4 tires on them.
