I just replaced an old pair of disc brakes from a 65 Plymouth B body to a set of new Strange disc brakes.
They didnt offer them for the 65 but thought the spindles were the same from a 69 Plymouth.
Brackets bolted up fine but the inner bearing wont go on deep enough to fit the locking nut with the washer and not enough thread engagement to put the cotter pin in.
Also the centering on the caliper cant be shimmed.

Are the spindle shafts different thickness for year to year.
Anyone have a solution to fix this mess.
These brakes are expensive and I cant send them back now. Please help. Thanks
