Help me understand this bolt pattern!

Biggest problem with all Cragar S/S wheels is the lousy soft washers they give you with their shank lug nuts. The washers are not properly plated so they rust. More importantly, they are very soft, and deform when you torque the lug nuts. Then the nuts loosen up when you drive the car. I believe McGard makes shank lug nuts for Cragars that have hardened washers, which solve that part of the problem.
