The headliner in the Town Landau consists on two cardboard panels separated by the center ceiling counsel. You'll have to take the overhead counsel down and some if not all of the interior headliner molding down to remove the panels. You don't need to take the windshields out.
Thanks, Gordie,
Mine is a base coupe. No overhead console. The headliner has bows. It's stapled 3/4 the way around. I was told I might have to pull the windshield because the front tucks into a slot behind the windshield, and the windshield seal helps hold the headliner. The one in it now is tore, but I don't want to take it out because I can't find anyone locally to put another in. Hopefully, come March, I can find someone who replaces them and drive it to their place.
Thanks
