Plastic/Cardboard headliner

Guess that we will never know. I believe that I am the 3rd or 4th owner of my '72 Dart, if it came with a cardboard headliner, someone found a used 340 Brite blue ( not painted ) ABS headliner and installed it. The rest of my interior is original. I replaced the orginal furry carpet with pile. Will be replacing the orginal cloth/vinyl seat covers and door panels with legendary parts when they show up. This car was a poster child of original till the previous owner gave it a paint job and changed the suspension. I have overhauled and is still stock 318 and 904 trans.
Was just adding my 2 cents, kinda got off track for the OP.
Merry Christmas and Happy New Year!
