Ok well, i got some fog lights and the retainers were missing, dont know what that is well maybe you tell from the photos below. Since I didnt have the retainers I made some from plastic 5/8" caps I got at ACE hardware. I had to drill a 5/16ths hole in the cap for the stem on the back of the fogs. Without this the fogs will not stay in place. You cant buy these from Toyota, they ONLY come with the fog light kit.
