99 slk 230 top & window trouble
 

My 99 slk has a couple of problems that I would really appreciate some help with.

1. the windows (both front) roll up too far (about 1/4 inch) and get caught on the rubber seals. Can they be adjusted? I am afraid of breaking one of them.

2. The hydraulic cynlider on the driver side that lowers the top is leaking fluid. Is there someone I get another cylinder from at a reasonable price?

Also, what fluid does the roof use and how do I refill it?

Thanks so much for your time and assistance.
