Clutch & Flywheel Q?

Help, I just received my SPEC 11" Stage II diaphagm clutch yo fit my 164 tooth McCleod steel flywheel. The pressure plate matches two different bolt patterns on the flywheel. A wide pattern and a narrow pattern.

Which one is better to use and what are the two bolt sizes?

I noticed the wide pattern is a larger bolt than the narrow pattern.

The two patterns are the same distance from the center of the flywheel, just the three (two) bolt patters are narrow (closer together) small bolt and wide (much farther apart) larger bolt.

The ARP clutch pressure plate bolt kit I purchased for SBF fits the small pattern but the package does not state the size of the bolt. [img]/phpBB/images/smiles/icon_biggrin.gif[/img]
