DM flywheel: how much play?


I would like to build a package that includes:
steel SMFW, sprung hub dual friction disk, PP, TOB, and pilot.
Does anyone have specifics (year, Part #'s) for the GM F body steel SMFW and suggestions for the other stuff?
(Also, when I pulled the slave off the piston was caught half way in the cylinder, its my second one. I have a GM slave and hose on the way.)
Thanks!
