I haven't ever seen the original mirrors, not close up. Is it possible they are close to the same as what is installed, only upside down? And err, left for right.
I'm not suggesting they can be swapped that way but it looks close.
I believe federal guidlines for new vehicles prevented the production vehicle from toting the concept mirrors. My wife really liked the prototype mirrors and they actually went a long way to convincing her that I needed the ssr. Then of course it came without those cool high mount mirrors.
