Fenderwell headers too Close to Master Cylinder Line

they say this:

This 1965-70 Mopar booster bracket does NOT change the angle of the booster mount. It moves the booster up 3 ½” center to center with the firewall bracket slotted for an additional ¼” up or down adjustment. It moves the booster ahead 4” on same plane and accepts the standard 3 3/8” mount boosters. The pedal mechanism changes the pedal ratio to compensate for the power brakes. You will need a minimum of 18-20 inches of vacuum to obtain the full power assist from the booster.
