No tag on the rear end. My guess from looking is an 8.8". Nice Try. One reason I believe it is a 8.8" is that the 427 has pretty much destroyed it, unless the autopsy reveals something else as the root cause. The engine is built hot and my guess from performance in this weight of car is it's boosting about 600HP at the rears. 8.8" are OK up to around 500HP if everything is perfect in the unit. Brake discs are about 10.5", solid rotor. Sliding calipers, looks like Ford stock but don't know. Pretty much a generic 4 link front and rear, coil over. Car will be going up on stands in a week or two and I'm going into the dark to probably just pull the whole damn rear end out. Throw it on the bench where I can tear it down. Do an autopsy on it. Will take pics as I can. Allen
