F body 8 1/4 into an A-body

Dropped one in my car - had to move the spring seats, but that was it. I have about an inch of clearance between the tire and wheel well. Nothing rubs, and stock offset wheels work fine. It actually got my rear tires lined up pretty well with my front wheels. I had to have the shaft shortened, of course i cannot remember how much. Maybe 2 or 3 inches.
