w208 rear window stop position help

[unit504]

right the problem i have it on a 1999 clk convertible, the rear driver side window goes up and down all ok, but..!

when you raise the window all the way up to the closed position the window itself over hangs the stop point..! So when closing the driver down it hits the rear window.

It there any adjustments i can make to move the rear window just them few mm to the position it should be.

i think i have found out the problem..!

What i need to do is replace the "stop angle"
on the end of the window runner (part number A2086730312)
As apparently this part wears out over time.
