only negative is I think the front track on the later big-bolt pattern K's are a little wider...



Like Rocketride said, thats from the spindles/rotors. So if you do the factory type BBP conversion to a 67-72 A-body, you be at the same width.

I had the BBP conversion in my 68 K-member. Then I switched to just the 73-76 K-member. No width change and no engine height change either.
