Ford Exploder 8.8 rear axle....

So, in light of people thinking 8 3/4s are gold and now the same with 8 1/2, what's the deal with the Exploder 8.8 rear axle? How close is it to fitting under an A body?I don't mind relocating spring perches. No biggie. But if I have to get into shortening the axle housing, I might as well use this 9" I have already. So how close is it to fitting? Thanks.
