Detach the metal piece from where it is attached to the body underneath the rubber pieces that were just removed.
The side of the piece that is closest to the door opening should now be loose. The whole piece should now be slid farther into the drive through the slots.
Once you slide the piece toward the back of the slots, the side that is still attached can be pried towards the center of the drive on each side to remove it from the slots on the door.
