Hello peoples. Can anyone tell me what a original proportioning valve looked like on a gt v8 car with power discs in front.. I see in some of the parts catalogs when ordering front or rear brake lines that late 67 had a pv in front near the distribution block. Than I see some rear lines that state with pv in rear of car for 67. Does anyone know where I can see a diagram showing the locations etc. I am replzcing my lines and brakes and the lines I had in the front by the master looked like a bowl spaghetti. where did the rear pv get mounted and what did it look like. Thanks I hope some of you garus can shine some light on it for me. Thanks in advance.
