The Stovebolt Site Forums The Shop Area General Truck Talk window wont stay up

I own a 1957 3100. The driver side window wont stay up.It slowly creeps down. :confused: What do I need to repair/replace? I need to replace the glass and the vent frame and window anyway so I can make this repair when I do that. So what do I need to do so the window stays up once I fix the glass? Thank you.
