Oh, and don't worry about the "it's one tooth of stuff." The distributor doesn't care where it sits as long as its housing is rotated to the correct position. A timing light will tell the tale. By this I mean if you put it off 2 teeth (assuming you still line up the oil pump shaft) and then rotate the housing the span of 2 teeth over, it's all the same to the engine. It may be that the vacuum advance causes interference, but the engine runs the same.
