Welcome to CHR! I've not messed with a Chevy of that vintage, but the only door glass I did long ago just had a strip of flat rubber, almost like a tire inner tube with the width equal to the inside measure of the channel. Seems to me that to get the frame off I used a piece of 2x4 against the glass and rapped it with a hammer. The channel was narrower at the open side, making a tight friction fit pinching the rubber to the glass.
There's several YouTube videos of door glass on Chevy trucks of that time. Have you done any Google research?
