Review on 🚗 Chevrolet Chevy Trailblazer 2021 Mud Flaps Kit - Front and Rear Mud Splash Guard Set of 4 by Emilio Wallace

Only 2 screws on the valve had to be removed. Two valves were with 3 ports available. So for the third bracket I just drilled a small starting hole, used the screw in the package and it went in safely. On the back you need to unscrew the screw in the wheel well and then under the car unscrew the screw that matches the hole in the cover and put the bolt back. Very easy. I hand tightened everything as I didn't want to use a drill and accidentally overtightened and "tidyed up" the hole. For the thick one under the valve in the back, I REALLY tightened it with a drill.
