Since 2013 the GT and V6 have the same front fascia. Prior years they were different. So if it fits a GT it fits a V6. Whether that particular grille requires a surrounding piece I don't know. It should be as simple as pulling your old grille out and sliding the new one in
That pic does have the surround. So you would be fine mounting that in your v6.
Now if you want to run the fogs you will need the gt support that goes on the inside of the bumper cover. Otherwise you will have to fabricate some sort of bracket to hold them. I have seen guys do this to mount them in the center so I don't see why you couldn't do it in the factory locations.
