R 129 Top Locking Cylinder replacement

[FiremistSLK]

As usual...after 63,000 miles, my driver side, top locking cylinder is leaking! I purchased the replacement cylinder and would like a step by step instruction on how to remove the windshield molding to get to the cylinder. I see the little black cover over the locking pin hole, but where are the rest of the screws I need to remove from the top windshield trim to get to the cylinder? I know alot of you guys have done this job, so could someone help?? THANKS, John D
