1967 was the first year for disc brakes and the dual master.  All cars in 1967 had a dual master with a distribution block. 1967-69 factory disc brake cars 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 on disc brake cars and a single block on drum brake cars.
