I'll have to deal with this issue at some point, unless I can convert to a regular headliner.
My car came with the hardboard, but a po put up what looks like a headliner made from a bed sheet, removed the dome light too.
I found the plastic chrome ribs in the trunk, didn't know what they were, almost threw them out.
They're brittle, and I think a few breaks on some of the ends.
If these pieces are hard to find, not reproduced, and old and brittle, I'm curious too, what are the final solutions that you guys are ending up with?
