Mirror, mirror on the door(s)......

I've heard the passenger side mirrors are almost useless since the wing window frame is in the way to really see anything. I can't stand the look of just one mirror so I'm adding one to the passengers side of my 68. I drilled the holes in the same location as the drivers side.
That's why I used some tape to position it before drilling holes and mounting it.
The position shown by dibbons pics allows the vent wing to fully open, and be able to see/use the mirror.
