How to swap from the big tripod mirrors to the small car-type ones?

[Frizzle Fry]

I went from the gawdawful towing mirrors to factory sport type on my Burb. Just three holes and a threaded backing plate. I called a local 67-72 parts shop to get the proper locating measurements (don't have them with me now). The passenger side mirror is further back than the driver's. Someone here should be able to give you the measurements from the front edge of the door to the forward hole for both sides if you want them in the factory locations.
