Part #: 800-128/129-128= Left
New rear brake wheel cylinder for Datsun 240Z, 260Z and 280Z for years 1973 to1976. These are a direct replacement for mid 1972-76 and can be used on the 1970-72 if you use the new brake line we have available or by the "bend it yourself" line. We have personally installed these brake wheel cylinders on a 10/1971 build date and with the new brake line they work great. Choose from right or left.
