The Daihatsu Charade hatchback car has a rear shelf that lifts when you open the back of the car.  Rods on the shelf sit inside plastic clips on the speaker mounts behind the rear seats.  These plastic clips can break, and if they do the rear shelf rattles while driving.  This design is for replacements of those clips.  There are two, which are mirror images of each other, so to make the correct side, the design may need to first be mirrored.
