  I second the comments of David Schwarze. The '72 does need to have a two-hose
  vacuum diaphragm to pass smog check. If you had a Bosch 009 installed and the
  timing set to 5 degrees ATDC, where the smog check guy is going to put it, if
  it isn't there already, you will not get anywhere near the amount of advance
  required at higher engine speeds. This would a) make your bus really slow b)
  give lousy gas mileage c) all the fuel burning at the wrong time and not
  being used to make the car go is turning into heat absorbed by your engine -
  making it run hot, the enemy of long engine life.
