Awesome guys, I was just lost and was wondering what the heck I am suppose to with these stuff, well thanks for clarifying. I already have 4, when I stripped the truck I only saw 2-3 metal plates and one inside the cab, did not see any of these busings at all. But why 4 more though I only have 4 bolts in total for rear mounts. Probably I am missing something.
