^^^ Yup. Unless your flywheel has been drastically shaved down, then the tool isn't really necessary if you have common sense. A Sharpie marker works well too with some electrical tape wrapped around it. It's amazing what you can come up with when you have an issue at the track that's a 4 hour drive from home lol. But I have found with severely lightened FW's the clutch disk like to fall down when using a stub/marker/extension since the lip around the edge of the FW will have been shaved off - it's even worse with a 4 puck.
I'm surprised no one has mentioned the pilot bearing. The auto won't have one installed in the crank and the trans will make a racket if it's missing.
