Went to a local tire, wheel, and muffler shop today to get a new set of lug nuts. You would think a place like that would have plenty of lug nuts on hand, and would be willing to order whatever you want. They looked at me like I had a third eye when I told them what I wanted. Whatever... 7/16 tapered bulge open nuts. Seriously.
Mounted the electric fan today. Now just gotta wire it. I hate wiring.
