I JUST spoke with Lee at McLeod. They have confirmed with Ron Fruchi (sp?) at ARP that the correct bolt to solve this issue is either the ARP 150-2201 or 250-2201, depending on the strength bolt you want to use. You MUST have a shouldered bolt that takes advantage of the counterbore in order to achieve reference, provided you have no dowel pins to create reference.

He says the bolts I have were not supplied by McLeod but by Fidanza, though I do not think that is right because I bought my Fidanza new from a local guy but there was no box, only a shrink-wrapped flywheel and paperwork, and no bolts. Regardless, we now have the McLeod recommendation.
