Thanks for that. I am thinking I will do the same, just leave it for now; it is mostly going to be used as a steep, perhaps some offroad but not much rock crawling in FLA. The cap was not obvious to me and I must have missed it in the installation video. They really should have some pictures.I ran into the same problem and just left it out. Found out later there is a plastic cap on the frame you need to remove before install in order to use that long bolt that goes all the way through the box beam of the frame. I put my mine on last September and have had no issues with just leaving the bolt off.
