66 Dart driver's side mirror not same as 67 up?

Not sure if you solved the problem but I stumbled across a spare 67 barracuda remote mirror. My #'s arent stamped as clearly as yours but its same # 2802301. Mine is missing stud(threaded hole) and missing the screw at the back end.
Cable length is a little over 29" measured from bottom of mirror base to threaded bezel that goes on door.
# on gasket 2802303.
Hope that helps.
