Pull your CPS sensor as well, normally if one is chewed up, so is the other one.

Yes I checked the crank sensor and it good. No marks No damage. It was something else.

Yes, Since I have to get a new flywheel, does anyone have a recommendation for a nice light weight flywheel?

Aasco should be a good one. Mine is on a way, so no first hand experience yet.
If you install this, the clutch disc should have spings to take off some vibration and / or balance the rotating internals of the engine.
