A friend of mine had a 2003 Grand Prix GT sedan with sunvisors which had plastic rectangular extensions that slide out of the end. They appeared to be original equipment but I have not seen any like them since he sold that car. I have a 1999 GTP coupe and sure would like to find a pair of those for mine. It has the usual lighted mirror setup but no extenders. Anybody know what cars these came in so I can have better luck finding some?
