I sent my last slave cylinder to Bill B. at ZFDoc, and he took it apart and blessed, maybe he still does this. It was the second one in 18 months, the first was assembled wrong. You don't want to drive the car untill this is fixed, make sure you use the GM fluid in the master and it would not be a bad idea to change the trans fluid as well.
