Came off a car ('72 GS) that the brakes worked. I'm assuming it's a repro booster. Don't see any markings on the M/C. Something must've gotten sprayed under the hood & there's white speckles on the booster that won't "buff out" but it would look great on a driver. $60 plus the ride. Located near Baltimore, MD or free delivery to GS or BCA Nationals
