Hey guys, on my left side running board, the backside "endcap" is lose. I have noticed that one screw is into the body, but there are two? screws underneath the truck itself. I only have one screw, and it is lose, so my question is: How do you tighten these screws at the bottom. I think you're supposed to use nuts, but does anyone know what size? Thanks for the help.

 

Just lose the running boards and gain the imaginary 1" lift.
