Re: 67 hub diameter?
If your disc brakes are stock, then you need a 2-piece rotor hub OR onna the new 1-piece cast rotor hubs to use with 4-piston calipers.
This is b/c the 4-piston caliper pads are radially wider than the single piston caliper pads so the hub has to be smaller in overall OD so the rotors OD still remains the same.
The later '69 one's use the big single piston calipers so are different b/c the hub OD is bigger around.
