So as I may be the only one to do so, I put the Gen2 stock wheels on my Gen 1. Just in an effort to mix things up, I removed my 20" Glamis wheels and Toyo MT tires and went back to the KO2s. I discovered that despite the wheels being Gen 2 you still need to use the Gen 1 lug nuts or their aftermarket equivalent. I reached out to Summit Racing (SR) as I have used them for my previous OBS 7.3 PSD for a number of things and they sent me just what was needed. Ford told me to also look after market as they sell the OEM Lug Nut but at like 7.99/nut. I got 24 from SR for about $38 shipped and they came quickly. So I wanted to post this, for what it is worth. Happy Holidays!!
