Here is the bracket so many of you asked us to make, it works on the Cab & Chassis 14 Bolt Axle ('73-87). This bracket uses the '75 Chevy 3/4 Ton Front rotors and calipers just like the rest of the 14 Bolt Disc Brake brackets we make, it simply has the different offset required to run on a Cab & Chassis Axle. These make the 14 bolt Disk Brake Conversion easy! They are sold in pairs and made of 3/8" plate. They are bent and do not require spacers like the ones other companies make.
