Need 4-speed Help

It's probably been mentioned, but I'm on autopilot. Before putting it all back together, it may be good to blast the splines on both the clutch hub and input shaft with brake cleaner. It's amazing how much a tiny amount of grit/crud will do. I'm assuming that this is a street/strip clutch and not some violent race-only unit. The latter tend to rattle your teeth loose when used gently (stiff or unsprung hubs, thin marcel, etc.). Smooth and properly aligned linkage is crucial. I'm not sure whether or not the fingers on these are adjustable or if that's a Fnord thing. Make sure that the throwout bearing and the fork pivot move smoothly.
