Advise on broken grill holders?

Greetings, I have a 2007 Limited 4Rnr 6cyl. (bought new in 07), 122K KM.
Modifications - I had a Pioneer Avic 6000 Nex radio/gps/backup camera installed a couple
of years ago, need to put new brakes on her soon and another set of tires, other than that she's pretty much the same as I got her. Fantastic vehicle!
Only real problem is it looks like someone tried to open the hood by pulling up on the grill thus causing some of the holders to break - I guess I can go to the dealer, but anyone else have this happen to them and any ideas as to a fix I can do?
Cheers.

 

zip ties, works for 3rd gen

 

Thanks, that's what I'm using now - seems to be the only solution (except replacement).
