Thanks - are the channels connected to the door anyway other than pressed in the door channel? Do I need to remove the door panel to get at any rivets/screws in the rear vertical channel down from the curve? I like to have a plan before I get into a project. The ones in my Suburban are probably the originals - hope I can save them - but being 50 years old they probably won't take the flexing - kinda like me
