What I said about the Suction Cups was just the way that I did it. When the Glass was not actually being removed or being put back into the Rubber it was over a Blanket on the Trunk.

I did not use the Suction Cups to pick the Glass up and move it from one place to another; only when the Glass was on top of the Car.

Also I did not cut My old Seal because I needed to see if it can be reused.

When People buy genuine Mercedes parts it would be nice if they would try to identify who made them.
As an example the Steering Colum Lock I bought was made by Neiman and as it turns out Neiman/Valeo are part of the came Company and you can get them aftermarket and save a little Money.
