First gen' A-body had 2 different center links. 67 through 72 are all the same,
Then they changed in how the arms are attached so 73 thru 76 all the same.
on my 71 the centerlink did rub the pan.... not no more was cut down in milling machine then I smoothed it out... you can see where it was cut down on each inner side of the castle nuts. shed some weight in process :0)
