Unfortunately, I don't have a digi cam. The best I can do is describe it. Currently I am at the school's library and don't have the piece in front of me... so I will describe it as much as I remember now.

Its covered in black window grease, but if it were totally clean, it would be a white plastic with some metal parts. The size is somewhat smaller than a hot wheels car... I have a feeling that it goes to the rails of the window... but I;m not sure. I will try to find a picture through the archives if there's one.

The window functions... but when the window is all the way down, and I shut the door... it makes a sound as if the window would shatter. When its closed(fully up)... it sounds normal.
