Probably too late to respond to the op but if you see this, if the clutch bell is turning when you're trying to drive the truck it's not the clutch. If the clutch bell is not turning when the motor is reving up, it's in the clutch somewhere. Maybe the collet is slipping due to a loose flywheel nut. Maybe the shoes are worn out. just have to look.


Second guy, you need a manual. That'll show you what may be missing and how it fits together. What car are you talking about?
