66-69 B rotor Bendix
70-72 B/E rotors KH small bearing
73 up Rotor KH large, plus dia changes
Many combinations so you really need to determine what spindles you have. If 66-69 spindles that is your problem matching up either caliper or rotor. Both must be Bendix
Calipers and rotors are all lining up nicely now. That is NOT the problem NOW.
The problem is the outer race and bearings location in the hub seems to be outward more than other hubs I have seen in person. Its not giving me enough thread engagement on the jam nut and I can't even get the washer on any more and no way to put the cotter pin through.
