Windows do not line up, please help?

[C10CONFUSED82]

My 82 C10 windows had bad rubber seals around the windows, so I replaced them all on the two windows. Also the glass was not lining up also when I rolled the windows up. I am still having the same issue after replacing the window rubbers all the way around. When I roll up the window the glass always stays out of the tracks, I have to hold in place will rolling up the glass to make sure that it falls into the channels. Any clues guys as to what I need to do to fix this?
