Need an image of rear chassis vent detail

[ptashek]

Could someone spare a few minutes and post an image of the rear chassis vent from a running car, please?
Just need to show my restorer how it should look like inside... because none of us have a "before" shot.
If memory servers there's a good layer of some silicone-like stuff in there, shaped so that water can flow out easier.

Major thanks!



Edit: I've just realised this thing is well hidden behind some chrome trim on an assembled car :/
