I just purchased the 3 peice grill delete and installed it yesterday. The center "u" shaped section, that cradles in the bumper keeps popping up. Any suggestions on how to keep it from popping up? I've read using double sided tape works, but i'm just not a big fan of double sided tape. At $100, you would think it would fit nicely. The americanmuscle.com version looks like it has 2 big retaining clips that slide onto the bumper to hold it down...shoulda shopped around more.
