1969 Power Drum Brake Help!!!!!

[Matthan]

 I have a 1969 Dodge Charger 440 I have Power Drum brakes all the way around. It has new drums and shoes, new master cylinder. the Rear Brakes are grabbing and making the Charger slide. Someone told me I might need a new proportional valve. Where would I get one for power drum brakes? Year One said they did not carry them? The proportional valve i have on my Charger has 5 lines going to it.

In Line Tube has what I  need!!!!!!

Drum brake cars don't have proportioning valves. The brass block is just a system splitter and has no proportioning function.
