So my wife ran over a curb this morning, not sure how she did it, but she did. On the underside of the X on both the passenger side and the driver sided, are these long black plastic pieces that are held in by some type of screw or rivet. When my wife ran over the curb, the passenger side piece broke, and a few of the rivets fell out. Any idea what these things are, and how big of a deal this is? Pics attached. I put a piece of tape on it just to keep it from hitting the ground temporarily, or it drops to hit the ground. I got under the X and no other damage at all, no scratches or anything, looked like she just must have rubbed this plastic part on the curb. Wondering also if anyone knows if this is something I can fix myself, if so, where to get the rivets, or do I need to take this in to a service center? Any help would be appreciated!
