There are a bunch of butterscotch (brown?) interior pieces on Ebay at the moment. Do a search on 240z and scroll down to find it.... Here's an example.

I don't know this seller, but, I know these colored interior pieces are hard to find.

Oh, of course I know him!! He's a member of the club... Bob Zola.
