Forgot about that, but Oldmanmopar is dead right. The new conical seat version takes a special lug with a conical seat, and a shank to center the wheel.
There was a thread about this a while back. The proper lugs were out of stock at summit and jegs, and supposed to be only made by cragar, but they were found either on ebay or Amazon, I don't remember which.
Google conical shank lugnuts.
