Anyone know how to remove the rear window's chrome trim strip from a W124 (1993 300E)? The first pic shows the chrome strip (with the rust I need to repair).

There is a self-tapping screw on either side of the strip at the lowest point (hidden behind the boot lid and under a rubber trim which I've removed, revealing lots of dust!) - see the second pic. I've removed these but can't figure out how to proceed from there.

There is also a cover piece at the top edge where the left trim and the right trim meet in the centre of the rear window. I have slid this piece out of the way, but that hasn't helped much either. Anyone got some advice please?
