Cruiser, I’ve been casually following this post. I had just the opposite problem w my windows. ( btw, my cab is a verified 1950 cab, although I have my truck titled as a 48…long story there). Anyway, my windows would roll down by themselves, wouldn’t stay up. This was 10+years ago, and after some research found a tension coil spring type item inside the regulator had broken: the little 90degree end of the coil wore off/broke. Anyway, I rebuilt both regulators and used machine screws and nylocs to hold the housings together. You can see them in the attached picture, and I’ve include a pic of the offending coil spring….back then that spring was like $3. Good luck, Regards, Dave
