I am having a really tough time trying to find this part for my 85 euro 280se front doors. It "sandwiches" the toothed rail between the power window motor and itself. No part #'s and nobody seems to know what it is. Please help! Look at these 2 url's for pictures. http://www.geocities.com/radioman911/parts/wguide1.jpg http://www.geocities.com/radioman911/parts/wguide2.jpg
