explorer 8.8 in an a-body: experience needed

yup. no plans to narrow it.
what is the flange to flange width of a big bolt a-body 8.75?

if i can find an accurate number for that, i can see what were looking at as far as total width differnce.

also, the reason im worried about clearance to my exhaust is due to my 3 inch TTI system. with the stock rear, ive got roughly 1.5 inches of clearance at the youke to the pass side muffler. after spending the obscene amount of money for that system, id rather not modify it.
granted, id hav more clearance with a 2.5 system, and it would be quieter. and probably not hurt my power at all, either. anyone wanna trade a 2.5 x-pipe TTI for a 3 inch?
