Big Block Bellhousing swaps

It’s a 10.5 and the factory spacer and ball stud bracket along with the bell crank works fine so far. Not sure what kind of explaining I need to do.
When I tried it the bell crank was at a different angle and would bind up with the factory A-Body big block parts. It was in a 69 Dart GTS and all I know is that it would not work. Can you provide a couple of pics?
