I used this on a camper blank body for the F150 Stx model. Easy to install, simply pry the two clips to release from the ball joint. Do the same with the new ones to install them and press the clips to secure them. Ready. What I didn't like was that red was twice the price of gold. That's why I bought the gold ones. My RV is red, but I just needed it to function properly. You can always paint them red later.
