250c window rattle
 

I have a W114 250C Euro with roll up windows that rattle. I have replaced the window channel and small nylon glass guides without eliminating the problem. It is not the glass. I pulled the panel and noticed that the window lift mechanism has a metallic rattle but nothing is noticeably loose. Does anyone know the part numbers for the wear parts on the window lift. I would like to experience the solid thud when closing the door and driving that I have heard about.

Thanks for the info, I registered for the site. It works great and is clearer than the other one that I have been using. I'm still confused on the part numbers for this particular seal but will probably replace them both if the're not to expensive. I'm tired of the wind noise.
