Do you have an adjustable rod between the slave and the clutch fork? If not it's simple to Make one out of some all thread (used ~5/8 I think) and a nylock nut: just cut a piece of all thread, nicely round it where it goes into the slave and then use the nylock (round nylon side to fork) to adjust out slack with slave bottomed out leaving about 1/8" slop. To do this I put a clamp on the slave between the back of the slave and the end of the rod to LIGHTLY seat the slave piston, then loosen the nut while holding the rod with vice grips away from where the nut runs until the fork has about 1/8" of "rattle".
