Ok so here is my question how did you get the grill off. and for that matter how is it held back on ?
Do you mean the grille off the truck? Or the grille shell off the inserts?
To get it off the truck there are 4 bolts along the top of the grille that you need to take out and then two clips at the bottom. To get those out you just pull forward.
To get the shell off the insert there are tons of clips that all have to be pried off with a screw driver until you can pull the insert out. Then to put it back together the shell just clips back on to the insert.
