1st pic shows 1972 school bus with a Midland vacuum booster and dual outlet master cylinder. Pretty rare combo from what I have seen.. This is same booster I had in my 67. You can see the distribution block is nothing more than for the federally mandated brake light switch.

2nd pic shows the factory distribution block on my 67 c50. I'm using 2 of these and plugging the unused holes. 1 for a single line to the rear, and the other to split for the 2 front lines.

3rd pic is the part number for the hydromax pressure hose from gm: 25902725
