What are the dimensions of this bracket? How much does it move the booster out and raise it? Also, what is the length and position of the rods within the bracket. I'm looking at using it on a 1958 Thunderbird with factory AC. I need it to move the booster out about 5" and up 3.5 inches.

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.

Would this work on my 1969 Charger? I am going from manual drum brakes to power drum brakes Thanks Doug

Speedway part number 91031989. This brake master cylinder bracket is meant to fit an A body or E body. A Charger is a B body, so a bit different. It may fit with some modification. Here are some measurements to help you determine if it will fit: 4.186" front outermost front to rear surfaces. Booster side bolt pattern is: 3.5" center to center top to bottom (holes elongated) X 3.25" side to side. Other side of the bracket has smaller bolt pattern: 1.86" top to bottom (holes elongated) X 3.21" side to side.
