I got a '63 c60 with no working brakes. I took apart the booster and got everything moving freely, but the vacuum valve bolt holes stripped out, and while I waited for thread inserts, someone thoughtfully moved the parts, and lost the shield for the spring in the vacuum diaphragm. Does anyone know of a part number I can look up? Or a intact booster they are willing to part with? All I need is the cupped "washer."
