68LAR: I think that is the most factual post on here regarding the Poster's original question. An 8 3/4 can be okay but I think 68LAR's experience mimic what most have experienced. I've been lucky a few times finding twisted axles and other problems with 8 3/4's before they failed big time. That's in automatic E and B-bodies that were streetable, mostly low 12 cars.
