The factory valve is just a distribution block. Period!!!! It has the valve inside but its only for the brake light in the dash.



I can only speak from an '73 model perspective, but in the '73 factory service manual, you are indeed correct---only for an A-body. All the other models show an actual proportion valve.

Thus in replumbing my brakes in my '73 dartsport when i did a manual brakes, aluminum 2 bolt cylinder and line lock, i removed the distributon block and used theline lock to split the fronts. The rear was feed directly off the M/C. Car had discs fronts and drums rear (10"). I never had a problem with the few panic stops i encountered, but the rears would slightly lock first. And lets face it, in my application with 3.5" front wheels with 165r15 tires, the fronts werent going to do a whole lot.

Just my personal experience in modifying and doing a little research in factory systems---your experience may vary.
