I bought the tinted hood deflector from Mopar and installed it last night. The directions have you drill four holes in the underside of the hood and attach the two clips at the end. The paper says to drill the wholes very carefully. They aren't kidding! I had a hell of a time drilling through (broke one drill bit and ruined two others). I had to push pretty hard to do it. On one of the holes, I was pushing a little too hard when it broke through and now I have a nice little pimple on the outside of the hood.
Also, the two end clips are attached to the deflector with little plastic inserts as the "nuts" for the screws. I screwed the first one just a little too tight and it snapped in half. I was able to use a small nut and washer instead, but the clip needed to be attached to the deflector first (not to the hood as the instructions state).
Just thought I'd pass this on. The final product looks great, and hopefully it will keep some of the bug splatter off the windshield.
