This should be an easy one. I purchase the deflector for my koup and the clips provided do not seem to hold up. You have to remove the current clips and put these in their place and screw them in. I assume its suppose to expand when you tighten down to lock in in place. There is a rubber piece that is under the clips and Im wondering if that has to be removed for these anchors to work. Id rather keep the rubber in place but I tighten down on the anchors and they pop right out. Anyone installed on of these?? Thanks for any help in advance.
