Heres the pics of my 06 with the 08 grille.
up close
This is what i did to make it work

right side of bumper

left side of bumper
I made another slot were the arrow points 08 grille so the slots would fit and extended the outer slot aswell. once u have the grille on hand you can see were they need to be and mark the spots.I currently dont have the grille on my car cuz im painting it.
Here is what its gonna look like

half way threw spraying the red. the black that came on the grille bubbled rite of the left side. Very upsetting waiste off material. So im completely stripping it and waiting for my signal mirrors to come so i can paint together. will post after it gets done. Hope the pics help.
