A-body spindle height (64-72) remained the same. But I *think* I see where confusion
might arise? You mentioned 67+. Discs were introduced that year. There's a difference
between the drum and disc spindles, it's the thickness of the boss for the big upper bolt.
But it's on the face, not the overall height. Mill off the appropriate amount from a drum
spindle and you've got a disc spindle. HTH.
