Yes, some of the tabs come broken off from ET. Yes, when you first approach the install, it's daunting. Once you figure out how to install, you'll look back, slap your forehead, and say "duh, of course". I was in the same boat and thought it didn't fit and even made a youtube video to share my difficulty with Neal at ET. You'll definitely want two people, but can achieve install with one, but with a bit of difficulty. Start from one side, get the clip in, then start tucking the top edge into the little bumper flair/slot, moving left to right (if you started from the left side). Have your second person hold the left side that you just finished flexing and tucking tight against the bumper so it doesn't pop out, once you get to the clips on the right side, you'll now see they do line up to the clip holes. Pop them in, and step back. It's a very tight fit, but once you realize that you can flex the diffuser a bit, it sits nice and snug and perfect.
