Sorry Weeds, I should have been more specific.
My truck started its life as a delivery panel in Iowa. That said it must have been a "plain Jane" as the "headliner" was some sort of "jute" backing with a vinyl like face on it and was "glued" between the top bows with something that looked like black tar. The sides were covered with some "cardboard" that covered, and was screwed to, the upright post.
Here is a pic of the material front and back. If you would like a close up of the top bows I can get one as I have not done the interior yet.
