So, the threads on one of my lugnuts are toast.

I need a replacement but I can't seem to find the same design at O'Reillys, Autozone, etc. I have the 16" Talon stockers with the "floating washer" design. The only replacements I could find don't have that washer and instead are just tapered where they screw into the stud. I would hate to go to the dealer for a simple thing as a lugnut but, I can't find anything similiar to stock and am concerned they will tighten up the wheel appropriately.

Thoughts?
