I have an 04' verte and I think the fog light housing is different on the coupe/verte than on the Z06. In addition to the Z06 screens, I think the Z06 fog lights are attached differently to allow more airflow through the screens, thus the purpose of the screens.
I know the aftermarket stick-on sreens are simply for show, so if you want to install factory Z06 screens, I think you will need to change the fog light housing as well as that is where the screen frames connect/screw together.
I maybe wrong so perhaps some Z06 owners or anyone who has done this mod using the GM screens can chime in. :thumbsup:
