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.
