Headliner and weatherstriping questions....

If it is the pressed board style and is in decent condition (that the board is solid, not water damaged) it can be reconditioned. Repaint it or cover with headliner foam/fabric. My headliner board in my '74 Duster was flaking paint badly and I glued the generic white foam backed fabric onto the board. It looked pretty good. I don't have picture at hand. If you want to see pix, I would search thru files to find.
I have picture of trunk weather strip too.
