question about the factory brushguard install.

[Hummer23]

I bought a used factory brush guard off E-bay i plan to install. It only had some light scratches. Anyway it was used and came with no instructions or anything. I am making my own contact pads. I have determined I have the later model with the easily removable tow hooks.
Is that all you do is secure oem guard through the tow hooks and tighten down. I believe that is it, but I have no local dealer to refer to, so i figured someone on here would know
Thanks
