If your asking about the A body cars, then Yes to that question.
1965 to 1972 A body cars used the Kelsey Hayes disc brake system.
1966 to 1969 B body cars used the BENDIX disc brake system.
1966 to 68 C body cars, and 66-69 Imperial's used the BUDD disc brake system.
Mopar kept everybody in business, back in the old days.
