This pair of drum to disc brake conversion brackets will convert your 1953 to 1956 full-size Oldsmobile to front disc brakes. This kit will do what others will not; fit inside a stock 15" drum rim.
These pieces are made in the USA, laser cut from 1/4" cold rolled steel for excellent tolerance control. No machine work whatsoever is required on your spindle; it does not even need to be removed.
