These are the same mud flaps I bought for my new Model 3 and they look Great on the car! My set came with LF, LR, RF and RR letters molded into the inside of the flaps themselves. Some knock-off brands may not have these letters molded into the flaps. The directions that came with the set are a bit sketchy, but they do say to use the NEW push-pin inserts in the package rather than re-using the push-pin inserts that come with the car (there are two push pin inserts used at each wheel). I don't know why they sent a whole bag of screws because you only need two of them. The screws are used on only the front flaps and the directions say to screw the top of the flaps to the inner (plastic?) wheel well. I found that a 1/8" hole drilled through the flap and into the 3/8" wide lip of the edge of the fender actually secures them better than screwing into the wheel well.
