Need some help from forum members who have LS7 clutch in a CTS. Put in a new flywheel, pressure plate, disc and LS7 slave cylinder. All went in fine, torqued to specs. Installed correct pilot bearing(large one as indicated by how far input shaft protruded from front of bellhousing). Remote bleeder installed and bleed till I was tired of bleeding, no air bubbles. My problem is that clutch is not completely disengaging. Does this setup, since the transmission is evidently further back from the bellhousing, need a spacer under the slave cylinder to allow it to move the clutch fingers further for full release?
