Thanks to Nightstalker and Black06vette for pointing out that this crank has the improper # of holes ( 8 vs. stock 9 bolt) for a ZR1 clucth.
The crank will be returned to Callies and either refunded or remade.
Sorry for any confusion or if anyone was mislead. Its just one of those things, you would not think would be missed by a company of Callies caliber.
seems to happen to more than one of us...
