Camper Mirrors: mounting location?

[GruntMoanCough]

Hi all, I fitted some, ahem, ford mirrors on my crewcab project, based on most of the pics that I found. Seems to me that the mirror heads are too low for good vision on the passenger side, when they're swung in.
Also, though the lower arms are not correct, I figured I could move them closer together, to give some lift and make them look more like they should.
Flipped through the assembly manual and couldn't find the correct mounting hole locations. Wonder if anyone could measure the holes for me or have any suggestions or ideas.
Oh, and would this style camper mirror be available for a '69? Thanks.
