Have you tried your local scrap yards? I'd bet there are lots of "compatible" models (using the same mirror). I'm sure some of the "techies" on this forum would know which models and years use the same fixtures.
Off hand, I'd bet the Cirrus and Dodge Stratus are the same (but I'm only guessing). If you don't get an answer from someone more knowledgeable than I (If no moderators/techies] reply) you might want to try your post in
http://www.chryslerforum.com/forumid_11/tt.htm - the "Sebring" forum page. Good luck, Offon.
