Front receiver hitch on 2009 GMC Sierra

[McGuyverKodiak]

I would like to add a front receiver hitch on my 2009 Sierra SLT 4x4. There are 2 that I am looking at - Curt #31322 and DrawTite #65052
I have the fog lights and tow hooks. Has anyone installed this and what has had to be trimmed on air dam. Any pictures? The pictures I have found on Internet are on a Chevy 2500 with front license plate holder.
Thanks
