Hi, My name is Joe I recently took over a project my Dad bought a while ago. He purchased a 1941 Chevy Master Deluxe, when he bought it, it was all taken apart. I'm working on the doors right now and installing the window regulators. I have them installed on the correct sides (so I believe) and the Front Right and Front Left Windows are not rolling up all the way. When they are "rolled up" there is still about 2" to go. I looked at the gears inside to see if it was working properly and it seems to be. Does anyone have any ideas of what could be wrong? Could I have the wrong regulators? regulator cams? Glass? Thank You!
