I just bought a 2016 1500 Crew Cab. I bought Lund Side Step Rails for my truck, I understand the instructions and watched videos on how to install them. Now on the front mounting point for the rails, where the captive bolt goes into the frame, the hole isn't big enough. There's the outline of the big hole, but a piece of metal and a smaller hole inside of it. There's also a nut in the hole next to it where the other captive bolt needs to be. How can i get this to work on my truck. The spots in question are circled in yellow in the pic
