Front Disc Conversion-Proportioning Valve and Master Cylinder

Go to NAPA , ask for a master cylinder for a 73-76 Valiant/Dart with disc/drum non-power if you are going manual . Same but ask for power if you power brakes . About $38.00 with core . As for the valve there are several ways to go here . Classic Industries/Year one have them , as well as others . Or you can go with a Wilwood valve . Either way it's easy/peasy. Don't forget to bench bleed the master or you'll be in deep doo doo .
