Window Replacment on 1987 SL
 

I replaced the driver's side window of my 560SL, twice now. The first time, they used a non-OEM windown and there was a great deal of wind noise.

I took it to a second mechanic, who installed an OEM window, much better, but still not perfect....window noise at higher speeds. Any tips on how to create a better seal between the edge of the window and the hard-top?

There's lots of adjustments available on the windows. It's covered in detail in the CD manual - well worth the investment, lots on Ebay.
