My new 2014 Mustang 3.7 manual transmission in white with black interior just arrived today. I noticed that the rear license plate/frame attaches with 4 screws and that the top 2 holes were drilled in the plastic to the screw diameter. In other words the pointy tipped coarse thread screws do not thread directly into the plastic. The right hand screw engages a nut plate or something and can be tightened down firmly while the left hand screw turns freely with the fingers and cannot be tightened. Can anybody suggest how I can fix this. It doesn't look like I can simply reach up from underneath because its a tight space and a long reach. And by the way the 2 bottom holes are just dimple marks in the plastic, should I drill these or just get 2 more of those coarse thread pointed screws and put them directly into the plastic? Thanks for your help guys.
