Were those optional sport mirrors available on 1970 chevelles? I know that I have seen them on 1972 chevelles. I bought a set for my 70, but I am not putting them on because I haven't been able to find anything that supports the bullet style sport mirrors as an option in 1970. Also, do you notice on that picture that is linked above, that the mirrors are attached to the side of the door and not on the rail, like the chrome mirrors are. I think all nova and chevelle bullet mirrors attached to the top rail of the door. those mirrors look like they are off of a '73-77 monte carlo or something.
