Blake,
I'm not sure on this, but I think you are going to have to / want to pull the clutch, pressure plate AND flywheel.
If the engine is still in the truck, and it has rear motor mounts on the bellhousing, decide how you are going to keep it up, so to speak! A block of wood and a hydraulic jack under the pan hasn't killed too many folks.
Edit. Research indicates this engine is on a pallet on the garage floor
