Valve Notes:
For use on 1967-74 A-body Mopar with either disc or drum brakes. If your Mopar had drum brakes you had the valve to the right and maybe the texas shaped rear hold off valve. Some Mopar's had the texas shaped valve and the distribution combine into one valve so your car may only have one valve or the two separate pieces, see BLK250 for the one piece valve.
This is the distribution block that is mounted below the master cylinder which feeds fluid to all four wheels.
