i just double checked - afaik the early '70s kh disks used the #2/#6
sets shared with drums and late disks, not the #17/#16 of the big
bendix.

speaking of this, i spent some time looking for possible brake
upgrades a while ago, and i located a mopar rotor that rides on the
same #17/#16 bearings as the amc big bendix; 11 3/4", 5x4.5", used
[not exclusively] '72-'81 on big cars and small trucks.  i don't know
the rotor thickness, i especially don't know the 'hat' height, and it
would at least need a custom or modified caliper bracket and 15"+
wheels - but maybe it's a possibility for those 'troublesome' big
bearing spindles...

napa offers - or offered - your choice of phenolic, aluminum, or steel
pistons in their caliper rebuild kits.
