I am looking for a correct proportioning valve in good condition for my 68 Front disk brake/rear drum Cougar and the correct bracket that attaches to the bracket on the Pressure Differential Valve.

If you have something...email me at bates.brian@sbcglobal.net

 

You will need to either rebuild a stock valve or hope to find an NOS item. No such thing as a good used one unless it was installed fewer than 10 years ago. I'd take the stock one, gut it and install a Summit adjustable unit under the rear seat.
