A common problem with 360 faceplates, the USB hinge breaks off leaving you with a spring and a piece of metal. Unfortunately I have yet to come up with a plan to fix the memory card slots that no one ever used but this is a start.
After you fit it in place, take a soldering iron and melt the plastic back to the metal piece. If you fear you're tearing too much plastic out or it's melting too far down, add some plastic! I threw in a busted off bottom piece of a pin header pin.
