The 72 Hornet came with the KHs, so at repair time you gotta do
the math; conversion to modern vs. repair what's there. Since I
just had a leaking caliper, replacements were cheap, and the
rotors were good, the answer was obvious.

Wow -- never considered this! Never had a KH braked car before,
but you can bet I will look at this. The KH calipers are more or
less identical to the Bendix in overall design (one piston,
floating caliper, etc).  Even shimmed, I'd want the Bendix rotor
centerline to be very close to the KH... you don't want the
caliper up against the side of the guide pins.

Great idea though! Believe me, I will look at this when the time
comes. It's trivial to determine if this is practical with both
systems around to measure!
