Hi, I am trying to install my tow hitch but I don't know what size the bolts are that screw into the cross member behind the rear bumper cover. I have the bolts that secure the two braces to the frame and to the hitch, but not the ones that secure it to the cross member. Thanks in advance.

 

I had this problem when I first bought my truck. I ended up just buying the bolts straight from land rover and I think they came to like $20 or $25. I do remember that they're really large.
