Same problem, shank diameter is too big. I ordered the correct ones from Summit on back order. They say January but I'm not holding my breath. Good news is I'm still doing body and paint anyway so I'm in no hurry other than to see what they look like on the car.
Looks like you'll have time then. I saw the difference, but thought .087" difference might work in a used wheel. If you get stuck, you could hone the wheel with some coarse sandpaper, and use the nut with the slightly larger shank.
