Not only do you need a clutch spider grunt tool, you will also need the clutch holding fixture and a uber-solid work bench. The slickest holding fixture I have used mounted in a 2" reese hitch...it is ultra solid. You will need oxy/acetalyne torches to heat the nut and spider to be able to remove them without damaging the threads that WILL have red loctite on them. Last but not least dont forget to reapply the red to the threads during reassembly.
