We went to the one at Texas Motor Speedway a couple of years ago. Fun! Also, NASCAR teams were doing some practicing during the event. Bonus, Days of Thunder!!!
OK. You're not going to believe this, but I was able to get the GM Genuine fog light valance, new bought several years ago for this day. Hopefully, it will have the same clearance provisions.
I bought these LED ones from IPCW several years ago. The reverse lights come with incandescent bulbs, so I changed them to some intense LED ones. They are great, but I'm pretty sure they have been discontinued. Truck is in shop, so I don't have it handy for as installed pics.
