This will allow you to mate a 1970 engine with a post 1972 tranny, this is the bolt on one that doesn't require crank machining.

The rule of thumb is easy: in 1972 everything changed. In general, you can't match pre-1972 engine/trans with 1972-up engine or trans. There are allegedly adapters for the V8s (I have no experience) but if you want to cross that boundary, it absolutely requires careful research and probably modifications. I now have three nice bellhousings (1963, 1969, 1972+) and one of them is double-drilled, and I'm going to make drawings of the patterns (both sides) for ID and comparison. Don't hold you breath but I will do it.
