Outside mirror

1964 was the first year a remote-control driver's side view mirror was available on A-bodies. The 1964 mirror is similar but not identical to the 1966-'76 (plus '66-'70 B-body) mirror. The 1965 mirror is similar but not identical to the '64 and '66-'76 mirrors. The differences are cosmetic: slightly different housing shell circumference contour, a couple of different control knob shapes, a couple of different control knob nut shapes -- the overall size, shape, and mounting are the same '64-'76.

People saying the remote mirror was only '66-up are guessing (incorrectly) what it means that they see listings for reproduction '66-'76 mirrors.
