What’s the difference between the 67 and 68 2-piece rotors? I know the hubs are different with the 68 utilizing larger bearings. But what about just the rotor part?

For 67 you can still buy the rotor - Centric 125.61053, but 68 is not available. Kind of curious as I will want to be sticking with the original 2-piece setup for my 68 if possible.

The '67 version is for the Kelsey Hayes 4 piston brake caliper. The 1968 version is for the single piston 1968 - 1973 Bendix caliper. I do not have the specifications in front of me but I assure you every part is different and none will interchange.
