| This kit will allow you to rebuild all clutch master cylinders for the 70-83 z and zx's, as well as the 620 trucks and 510's. We also sell the master cylinders new. See listing. Even though the zx takes a different master cylinder, the rebuild kit is still the same as the older z's. If we happen to be out of stock, it usually only takes us a day or two to get more at the most. We can ship this anywhere in the lower 48 states via the postal service for 6.50. If you'd like that service just put a note in the comment section of the order form and we'll take care of it for you. Last update 10/11 |
