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.

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

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.

Will this work on a 1966 Dodge Dart that is factory equipped with power brakes? If modifications are required, how extensive as this car is freshly painted. Would you have a 7 inch (8 inch as an alternate size)"Dual Diaphragm" booster to function with the bracket?

Yes this should work on your 66 Dart as that is an A body type. You may have to drill some holes to get it bolted up, this uses 4 bolt holes to attach to the firewall. Part # 91031411 is the booster kit that we recommend with this pedal bracket.

I apologize we currently don't offer the factory firewall insulation at this time. We do offer a firewall grommet from Earls that you may adapt to work for your application, part number 42529G001ERL. We also offer Dynaliner in a peel and stick application part number 31011101 for 1/8", and available in 1/4" and 1/2" as well.
