HELP - Cragar SS Lug Nut Washers Keep Crushing - Need Alternatives!

If MobileCustoms strikes out on finding the correct size nuts and washers, a possibility would be to hone the holes in the wheels to fit the McGard PN 61001. That nut's shank diameter is .679". The Cragar nut is listed with a shank diameter of 0.592". That would be very little material coming off the wheel. As long as there is still room for what may be a larger washer between the spokes, it could be worth consideration.
I'm pretty sure the McGard is a superior product, and it's still made, for the most part, anyway, just outside of Buffalo, NY.
