There are two pieces of plastic, one on each side, underneath and ahead of the front wheels/tires. They apparently direct air into the brake area for cooling but also appear to be the first thing to hit in the event you'd scrape the bottom of the front of the car. They look to be easily replaceable and held in place by four fasteners. Coincidentally both of mine are missing the outermost fastener. The remaining three fasteners in each of them look to be identical black plastic pop rivets. Can someone check theirs and see if the outermost fastener is the same as the other three fasteners on each of their "spats?" Seems like a stupid question, but for some reason the outermost hole looks like it might be bigger. Just a heads up, the metal screw and washer you'll see is not involved with the plastic spat piece. There is a large hole in the plastic spat piece that just allows the plastic spat piece to fit over that screw and washer. Thanks in advance!!
