Guys:

Found the exact factory match flywheel. Half inch bolt holes, 3 dowel pin holes and all. Supposedly unused NOS off Ebay.

Ended up spending a pretty good sum of money after getting the owner to sell outright, shipping and cost of resurfacing. But still well less than half the 308.00+ tax GM wanted for a new one. Best of all, my new 11" Luk clutch set bolts up perfectly.

Good ending! Everybody wins! smile
