I noticed all the birds had chrome mirrors except the one that was driven. That one had color matching (yellow) racing mirrors. Were racing mirrors an option? I don't think I've ever seen a photo of one with them.
I believe that the painted racing mirrors were not available until March of 1970. The Superbirds had to be built by January of 1970 or they would not pass the newly imposed bumper impact standards. That is probably why you have never seen another Superbird with them. I would say that they were added when the car was restored. I put them on all my 70 Chargers. I think they look great!
