spoiler fog light

[emilo]

Hi everyone. ..
My first questions is almost embarrassing to ask but, , How to change the lamp in the front fog light (located in the spoiler)?? I've looked at the backside of the fog light and removed the plastic cover. Under the cover I found another plastic cover that I didn't succeed to remove. Is there a special procedure for this cover?? Is there a screwthread or just to pull?? It's very tight so I don't have much visual.

Second qustion is about the dashboard/frontpanel. I have to get beneath the panel to follow up some cables (probably going from the middle to the right) so my guess is to remove the panel at the passengerside, under the glove compartment. I haven't figured out how it's attached though. Is there something I should look out for?? The car is a 300 SL -91.
