Passenger side mirror?
there is two 67 barracudas here and two different mirror locations from the factory. One the vent window hits . the other is behind the vent window and it don't. Mirror locations match left to right. . I also had left and right manual sport style mirrors on a 69. No cables on either. My neighbor who gets most of the Barracuda parts kept them. The have factory bases but the whole mirror moves as the cheap manual style.
They did some weird things in those years. Like a 68 dash frame in a 67 car with a thumb wheel radio. No lower pads and no vin on dash. But it is a factory thumb wheel frame. One thing I learned over the years is never say never on these cars.
Something I learned when a member lou was here for a 68 radio bracket was. 68's had fiber optic ash tray lights . In all my years I never took notice to one on a 68. But I really never looked for one.
