Anyone happen to have the part number to these? Driving down the highway yesterday a passing car kicked up some sort of plastic debris. I wasn’t able to avoid and it smacked the lower right front of my bumper. Was able to rub off the marks with some compound but it broke the retainer clip that holds the parking sensor in place. Dealer parts counter claims they cannot find just the retainer and that I need to order the entire sensor. However this contradicts what I have been able to find searching the web. It looks like retainers are sold and are even painted from the factory, I just cannot find the one for the 2016+.
