Before the bellhousing is reinstalled, the clutch fork, release bearing, and pivot ball must be installed. We're using a Lakewood fork that's intended as a direct replacement for a GM fork, though it has reinforcing to better cope with heavy-duty clutches. The Lakewood pivot ball is adjustable to enable proper fork angle. Make sure the release bearing is properly positioned on the fork, then snap the fork over the pivot ball. Adjustment is made with the bellhousing mounted to the engine.
