After further trimming of the grille.

I used small bolts and screws to keep the grille in place.
Not the pretiest but reliable.

**If you choose to use bolts/screws like I did, You dont want the bolt or the nut sticking too much on the outside of the intake because this is where the lip of the air tunnel matches to fit. I chose bolts with very short universal heads.

Finished grille work! No more worries of pebbles causing bents on the radiator fins.
