I didn't mark and check to see myself.. Just didn't like how the bolt lug was inset from the grille edge.. meaning it was not going to be pulled down tight with a bolt. And the lower tab shoots upward.. meaning bend it down to get it angled right and still an air gap since you can't tighten it down fully. Got some springs to pull the bottom in and like I say making a couple brackets to run off factory bolt holes to the grill lugs at the top. Just me being picky I guess.. LOL
