Urgent W124 diesel windscreen help

[Kohlanta]

Hi guys,

I have a 1989 300D that needs a new windscreen.

It has gone in to get the glass repair done and they say that the one in my car has a cowling retainer and the one they ordered in the picture doesn’t.

Now they say they can’t get the screen with a retainer in.

I had a look at my screen and it appears identical apart from this crusty piece of rubber that is attached to the bottom centre of the screen below the wiper motor.

Can I do With out this and still fit the screen in the picture ? I can’t see why not and I have read before that you could still fit them ?
I just got the feeling that they didn’t want to do the job after seeing there was more work involved with these cars with the wiper etc….
