‘72 Demon cardboard headliner install

I have installed both the original pressboard type and newer abs headliners. The abs headliners are not fragile like the originals, and so much more flexible that it is an easy install. I did both installs on a Duster and Dart Sport, windows still in, with seats out of the car, through the door. Just had the door windows down and wide open, with a helper inside and I outside until we had it positioned. Basically the support points are the dome light housing, tucked under front and back windshield gasket, sun visors, rear view mirror, and clips like these at the door window areas. Also the shoulder belt strap clips if so equipped.
