so just a quick update for those that follow where others have already gone.
The 2016 grille has a support piece that runs along the top and sides of the backside of the grille. It it held on by 10 bolts. I used a 5/16 ratchet to remove them. They aren't hard to get off. Then there are 2 covers, one on each side, that seem to direct airflow. Those are held on by a slot and tab system. The tabs are hard to get out. It takes some wrangling with a screwdriver or other pry object. They are kind of robust, but don't get too heavy handed.
Now, once those covers are off, the real fun begins. The insert itself has another tab and slot system. This time, it's best to gently pry from the side of the tab/slot. If you do this right, you shouldn't break any tabs/slots. Take your time.
If you're shipping this to someone, the box I used is 30x24x6. My inserts went to CT from WI, and it cost me $35.00. Weight was about 7.5 lbs, give or take based on packing materials. I used bubble wrap and airbags.
Good luck! I'm impatiently waiting for my return package
