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.
