I am trying to install new window channels in my 1949 Chevy truck. I currently have the glass and crank out of the door. Old channel is out. I have tried window channels from two different vendors and have ruined both trying to install them. The problem I have is the window channels want to kink when I try to put them in the doors. I've ordered another set, but really don't want to destroy another set. They are getting expensive. Any advice or tips would be appreciated. I've watched the Youtube videos from USA1 Industries and they make it look like a piece of cake. Unfortunately, I have not had the same results.
