That whole mess with him was retarded. Rearend just plants the power. It will be our Chevy model. Chevy 327. Chevy Tranny. Ahh who cares. Do as we need to. If someone has a 9" laying around than use it, if we got an 8.5 use that, 8.8 would be prefered. If your worried about longivity, than get the aftermarket Non tapering Axles for the 8.8inch. And, it will be funny if we do have a 9" laying around, and the Ford guys say thats why we won, because it sucks up alot more HP than an 8.8 does.
