This hydraulic clutch master cylinder is a very close replica to the factory part that is equipped with a T-56 transmission, but utilizes a threaded rod instead of an eyelet. It is used in our Holley Hydraulic Clutch Conversion Kits (319-910 and 319-911). Use only factory recommended brake fluids for this application. DO NOT use DOT 5 brake fluid as it will not only cause master cylinder failure, but also damage to the clutch slave cylinder. This kit does not include the factory hydraulic clutch line disconnect tool (J-36221). It should be purchased separately before attempting to begin installation.
