ABS headliners

Not to derail the original topic, but could one of those ABS headliners be made to work in my 67 Valiant 2 door post? I have a roll cage going in, and there is no way I'm going to screw around with a fabric headliner and bows. Just wondering if anyone has done this before.
On a guess, I'd say yes....If one was made for a Scamp, it may work for a Valiant post car. The Duster/Demon/Dart Sport roof design is narrower and shaped differently. I don't know of the ABS headliner is offered for the 72-76 Dart/Valiant models though.
