Ok there is a hole in the crank and a hole in the flywheel is there some kind of pin that goes in it ?? "ordered" one for the GM dealership and i get the dowel pin that goes in the outter part of the flywheel to allign the clutch onto it he looked up different years and part # with no luck ...any ideas im gonna guess its about a 20 mm

No pin. It's just a hole to look at so you put the flywheel back on the same each time.

Yep. Kind of freaked me out the first time I did a clutch swap and took the flywheel off.
