On 68-70 b body I don't believe there was a non power disc brake option. And there was no proportional valve with drum brakes, only a brake safety switch block (aka distribution block.)
I think there were only 2 master cylinders, 1 for power drum and drum, and 1 for the disc. Depending on motor, lines exited on left or right side.

Year of your B body can matter. 67-69 Bendix 4 piston Disc had a proportioning valve, but 70 had proportion valve and Meter Valve for the KH single piston Disc. This ultimately got combined.
Generally Disc have the larger reservoir on the rear of MC for the Front Disc brakes, it also does not have a residual valve in the outlet port for the front disc. Only the Drums outlet. There were some Station Wagon Drum/Drum setups that used the Disc MC.
