I switched my grille to the HPD one a few weeks ago and I definitely recommend paying the dealer (quoted $180 labor) to install. I triangulated posts from the forum, a YouTube video, and the instructions from College Hills and was able to get it done in about 4-5hrs but it wasn't worth it. It was a lot work when you're doing this for first time. Also, there's anxiety of screwing something up as you are tugging and banging on a new vehicle. The "extra" screws and clips I had left over when I was finished didn't help either. One place I was held up was removing the bumper (step 12 on the CH instructions), I released the 4 retaining tabs with a pry tool and then was trying release the next 5 tabs with tool but no go. What you actually do with those is just pull the bumper, no need to release anything.
