Billet wheel adapters

factory 7/16 studs are weak, we used to have non car type customers twist off the left hand ones with the stock lug wrench all the time. " Oh, is that what the L means??"
My 1970 Swinger 340 still has the LH studs on the driver's side. I'm leaning over the tire guy's shoulder when it goes in for tires or balancing.
