All 1964-66 GM cars had drum brakes. The only option was power or manual brakes. 1967 was the first year for disc brakes and the dual master.  All cars before 1967 had no proportioning valve, just single master and a distribution block on the frame. 1967 factory disc brake cars also had a distribution block, but it worked in conjunction with a barrel-shaped hold valve that hung off the stud of the master cylinder making this a two part valve.
