Rotors available (for now) for K-H disc brake cars
proabbly find the rotors being wrong is due to the slight difference between US rotors and the Australian rotors that were used with a solid mount 2 piston PBR caliper
see this here
Front Disc Brake Rotor : VC VE VF - Solid Disc
got a fat band round the hat section
in thses days of globalisation has somone somewhere focused in on the australian part for 66 -69 Aussie 4 inch pcd cars with optional solid disc brakes, and decided it is suitable to be sold for all small bolt pattern cars in all markets? i.e nothing wrong with the casting, just the rotor you are being sold is for use on Aussie Cars
Just a guess.
the australians are not complaining about rubber dust boot damage.
rear drums the aussies used 9 inch and 10 inch rear drums 9 inch in 4inch pcd and 9 and 10 inch in 4.5 inch pcd none of them were darth vader helmet style.
