Since the stock clutch was toast we replaced it with one from RockAuto. The flywheel was pretty hashed and needed the grinder instead of buffing it with sandpaper. The stock step grind dimension is 0.20, but Marlin takes it down to 0.26 for better bite. With a new pilot bushing, disc, cover, and throw-out bearing, the truck should be able to wheel a lot better. Marlin also offers and recommends an upgraded heavy-duty clutch, but I took the broke kid approach on this one.
