The dash panel is screwed to the dash by screws that can be seen through little holes in the carpet over the panel (you have to have a close look to find the screws).

I have never changed the fog light bulbs...I can have a look tomorrow at my model "97 fog lights that are still lying on the shelf...and give you an answer if someone else didn't already.

greetingz,
