OK, maybe I'm not good with searches but I tried and did not fond the info I was looking for...

Has anyone installed the M7 upper/middle grills or the ultimate front grill? I just wanted to know how they install because I'm thinking of getting them.

 

The upper grille installs with two screws with nuts and is the easiest. It is best to remove the bumper for the middle and lower grilles. The middle grille may or may not require you to drill a hole depending if you have an arrow bumper or not. The lower grille requires three holes to be drilled. It's pretty easy, just line up the grille and hold in place to mark where the holes go, then drill and then install the clips and screws.

Easy as pie. You will probably want to paint the underling metal black to match though...

 

Here's the link to when I installed the lower grill.
