I've searched all the fog light threads. I have a 02 AV6 sedan. I wanted to know if the fog light mount should be on top or bottom of the fog light? And if drilling is required for the mounts. I know the plastic grill has to be cut though. I got some new piaa 2100 for winter just the other day! I'm trying to find the easiest way to install. Thanks. Pic's would be great too!
