Window Trim on 94 Accord

[94_Accord]

hey all, the rubber surrounding on the outside of my drivers window has gone. it was loose on one side for some period of time and eventually the rubber trimming snapped off when i was putting my window down..

i just want to know if anyone knows whats involved in replacing this, and what needs to come off / out in order to fix.

thanks

the pic below is the best i have to try show you all what i mean, notice the trimming on the outside of the drivers window is gone.
