Outside mirror
The same manual sideview mirrors optional for the driver's side could just as easily be installed on the passenger side. The most common one was a 2-post item, part № 2299 574, that looks like this:
Less common was the larger police/taxi manual sideview mirror, part № 2292 194 (plain) or 2292 195 (tinted "nonglare"), also installable on either side, that looks like this:
If you're asking whether there was a passenger-side counterpart to the driver-side remote-control sideview mirror offered in '65, the answer is yes. It was a "reach out the window and move the glass" manual-adjust item with the same design as the driver-side "leave the window closed and move the knob on the door" remote unit. Part № 2525 938, superseded by not-quite-identical 2809 933 (which has the outboard housing extending rearward to provide more shading to the mirror):
Note the '65 driver-side remote mirror is not the same as the '64 or '66-'76 driver-side remote mirror. They'll all fit in place of one another, but the styling is different. '64 mirrors also listed in the '65 FPC have a ridge/lip around the circumference of the housing that's not present on later mirrors, '65 mirrors have outer housing sidewalls that reduce in diameter from front to rear, and '66-up mirrors have straight-back outer housing sidewalls, same diameter from front to back.
