For informational purposes, I thought I would update my post. I answered my own question - the bottom 2 "blanks" pop out easily. I bought a license plate screw set from the local auto parts store and it came with extra plastic inserts. One gripe that I have, I had to add plastic washers behind the license plate to keep it from hitting the paint on the car. In the end, I now have 4 screws keeping the license in place and not clattering as the hatch is closed.
