I saw a writeup on how to install a glass rear window in an S2000 that has a plastic rear window. I think it is something I'd like to do. I can't find the writeup (bookmarked @ work), but while I'm thinking about it - where can I get a piece of window glass to put back there? The writeup said there was no defroster - so I know it isnt from an 02+ S2k.
