I have a 2017 JKU Jeep. After removing the front bumper and beginning the installation, I found that the wiz nuts did NOT go through the holes in the front bumper mounting plate, the holes were too small, and/or the wiz nuts were too big. For real? At this point you have two options: #1) grind the wiz nut to go through the hole in the plate, or #2) grind the slot in the hole in the plate to allow the wiz nut to go through the frame fits. I think option 2) is the best. The grinding of the nut itself (option 1) changes the contact area and possibly the character of the mother metal (due to the heat caused by the grinding). Not a big deal, but a factor.
