I am missing one of the footman loops in the rear cargo area - I just have two holes in the floor. I have a matching loop but no attaching hardware. Can someone tell me how they are attached? The remaining ones are covered in bedliner which I do not want to remove. It does not appear that I can get to the bottom of this area of the floor without removing quite a bit of other stuff. This is on a 2003 Wrangler.
