sunroof leaks

[will white]

1985 300D, need info on location of drain tubes and how and where they drain? on the drivers side I have a leak at the top of the side post and headliner area. On the passenger side water drains out in the middle of the jam area of the door. I'm sure the drivers side drain tube must be off, I tried to remove the front headliner but got as far as the rear view mirror and I don't know how to remove it. need help!
