How to remove door glass and vent windows on my 51

[Elvis51]

Well I have been lurking in the shadows for a while but never post but finally started my complete tear down of my 51 five window to get it ready to send to the sandblasters but I can't get the door glass and vent windows out of the doors. I have removed every screw and bolt I can find. Any one have any advice or pics showing how it is done. Thanks in advance for the help. I have changed out alot of things and worked on alot of cars and trucks but this is my first true frame off restore and already floundering.
