73 Dart Sport headliner

Anyone installed the new full piece headliner in a Dart Sport/Duster that replaces that old hard cardboard(or what ever it was) one...mine has a temoprary one in it just to cover the ceiling but even when the wife rode in it on Saturday she commented that it needed one....hopefully now if I mention it to her I can get it :).... just wanted to know how the install went(do you need to remove the window(s) ) and how you like it.
