With the headache of all of the hard-to-get-to fasteners holding the grille in place, and the high risk of scratching everything near the grille upon reassembly, I would be tempted to remove the entire front clip as a unit. Also in the mix is the rust factor involving the ubiquitous fasteners holding the grille and other associated parts in place. I have read that it is not too difficult to pull off with two people. It would also seem to me to be much quicker. Not that many fasteners holding the front clip to the truck.
