1965 valiant. Looks like a type of cardboard for the side panels and package tray by the rear window. It will by covered by the headliner. Not sure what kind of material to use.

I think it's some variation of masonite, which I've used for that, same for spare tire well covers...just different thicknesses.

I used some stuff we called beaver board back when I was a kid. Its about 1/8" thick, very smooth on one side, and kinda rough diamond-plate looking on the other. It is moderately flexible. It comes in sheets as big as 4x8.
