Vacuum verse mechanical

Does any one have any documentation on what cars got the vacuum systems and what got the mechanical systems? I have seen original big cars with manual transmissions and vacuum tri-power. Never really paid any attention to GTO's with automatics but don't recall seeing any vacuum systems on the GTO's.
