A Hotchkis front sway bar for a '67-72 K is in fact a direct fit for that combination. It will work with both the '67 K frame AND the later end link tab locations used by the QA1 LCA's.

You can clearly see that both end link mounting tabs are in the same general location on the LCA, inside of the strut rod between the shock mount and the window for the torsion bar adjuster. They may not be identical, but they're more than close enough for the endlinks to take up any small difference.
