1989 Bonneville SSE RH mirror

Try Ebay. There's always lots of vintage auto parts for sale there. Rockauto.com might have one too. Good luck with your search, hope that helps!

Thank you but I've been constantly looking there. The SSE model is unique in that the mirror is body molded and rectangular in shape. Vastly different than any other Bonneville or GM of that vintage. My hope is that someone might know of a bone yard someplace where there is one of these that hasn't been crushed yet.
