I tried to find an answer on another Mustang site, but no luck. Can someone explain why Ford had two different motor mounts for the 67 small block Mustangs. I see that some are called tall mounts while others are called short mounts and the tall mounts are for convertibles while the short mounts are for coupes and fastbacks ( I think I've got this right). In the end it seems to have nothing to do with engine position in the engine bay.
