I have some questions about paint code plates.    1. Can someone tell me where this is paint plate supposed to live?  I read that it should be on the LHS door pillar (A pillar?). I can't find it on mine.  Anyone have a photo of theirs?    2. If anyone has a Grand Prix White car, what does the code look like on the plate?    3. How big is the lettering that is stamped in?  I.e. letter height, so I can get the right size stamps.   Thanks.
