This pair of precision CNC laser-cut, cold rolled steel brackets are used to convert your rear drum-brake equipped 1964-77 intermediate Buick rear disc.  This setup uses 1980-85 Citation caliper with 1998-05 GMC Jimmy 2WD rear rotors which areuse a drum-in-hat style emergency brake - and are as near as your closest NAPA or other parts house.  We supply the brackets, parking brake shoes and some hardware.

The axle shafts do not have to have the flanges turned down to fit inside the rotors.  We have a flex hose retainer welded to the bracket itself, so no welding or cheap zip ties to retain the hard lines.

You will need to modify the rear brake hardlines and parking brake cables.  This will require the use of 15" disc rims.
