The details
 

So the grille mod is super easy. Couple of things you may need.
Hack saw blade
Files
sand paper
gutter guard home depot 1.47

good primer

I had already painted the grille black before the mod. The grille was chrome when i started. I sanded the chrome with 100 grit sand paper to scuff it up good and then 150 and 320. From there i primed it with a lacquer primer and then three coats of paint. Followed by three coats of clear.
Then i saw this mod

So basically what i did was cut the center part of the grille out with just a hack saw blade. Then filed down the nubs that were left. From there i sanded down the rest to get it smooth. The gutter guard install was pretty simple.....layed it over the back cut out the factory clips where it mounts to the truck. by the way leave those when you cut the grille out. Then drilled some holes in the bottom of the grille and used zip ties to hold the grille in place. screwed the top of the gutter guard to the mounting brackets and here we are now. i will take some pics when i take it back out to finish up today.
