I replaced my grill with a 3 bar recently. You can simply release the top of the bumper to get your hand in to reach the top clips, and remove the lower bumper grill and reach up to get to the lower clips. I used a screwdriver to break all the grill tabs on the bottom edge to remove it, didnt want to keep/sell it so not an issue breaking it to remove it. The 3 bar grill then just pushes into place pretty much.
