72 duster Build progress

Which headliner are you gonna put in the cardboard or the older perferated material type?

The factory one I took out was cardboard and was junk, I see they remake the hardboard liners for these dusters in abs plastic but allcriptions say "uncovered" I don't know if that means you get just a textured black plastic headliner that is not covered in any sort of material or what? I am not sure exactly what I will be needing and what route I should take? Any suggestions?
