Picked up the Black Honeycomb grill insert (Part #68143074AD) for my 14' Altitude. This is the grill that should have been installed originally.
Followed the top down install method which took about 45 minutes to complete. I did remove the two plugs on the top pad first which gave me the ability to pull the outer grill away from the Jeep. Like others have said, your arm will endure damage due to the plastic, but its not totally bad. I started with removing the center inserts. I found that I could pull the outer grill away from the vehicle while pushing between the outer and insert with a screwdriver. It seems like the force was a lot but the inserts would just pop at their connection points with no damage. To install the new inserts I started with the outer ones first.
Again, it took 45 minutes with this approach and I used two different length flat head screwdrivers as suggested in this thread.
