The issue you’re having is with the 3rd screw. Prior to magna grips that screw head is domed and proud of the frame. On later models the screw is flush. Mark the screw with a sharpie and tap the grip panel over the screw to transfer the marker. Then take a drill bit the size of the screw and remove some of the material. With a new bit you can do this by hand. That will close the top gap.
