Plate, booster/master cylinder mount, formed. The booster centerline is 4-1/4″ off of the boxing plate as shipped, but the bracket can be trimmed to move the booster closer. The bracket will mount Ford or GM manual master cylinders and either 7″ (single or dual) or 8″ dual boosters. Booster mounting holes are 3-3/8″ x 3-3/8″. Designed for our WS24806 kit.
