Does anyone have a source for a headliner for a '67 Belvedere Sedan (2 door post car). I've tried most of the major suppliers, but they only handle headliners for the 2 door hardtop.

I'd be interested in this also. I haven't tried to locate one, and didn't realize they are hard to find. I'll need one in the future.

Also curious about the plastic trim around the back glass. Mine is disintegrated. I'm sure no one makes it, but wondering if there is some kind of substitute that will work.

There are several interior companies on eBag, I've chatted with several of them, and I've asked about other specific colors they don't have listed and they've basically said "they can make it".
I haven't asked about a 2dr post before (I have a 67 Sat 2dr ht) but have you contacted any and asked them?
