LCA's are all the same from 1962 to 1976.
BALL Joints are different.
You will need lower ball joints from any of the 73-76 A body line of cars, for a disc brake swap.
Unless there's a factory sway bar. In which case, the location of the sway bar end link tabs is different between the 67-72 and 73+ LCA's. Not sure if the 62-66 are different again from the 67-72.
