You'll see a square hole over the flywheel to view top dead center marks right by the reference sensors. They have a tall 10 mm bolt. If they have never been out, they can be a pain, and sometimes break. Spray some PB Blaster on them and let them soak. Wiggle them slowly until you can pull them.
He said he did have tach bounce, though.
