Am I sure? Does a bear, never mind. I hopeyou can see what I am talking about. With the 71-72 calipers being floating calipers, they may center on the rotor and this may be moot.
The first pic shows that if set on a hard surface, the mounting bosses are equal. When turned around to face each other the difference is seen.
