Thank you for the information AZKen. My main concern is the distance from the [cab] ceiling to the mirror itself. Will the mirror hang down low enough to not have obstruction with the smaller rear window? Unlike the larger rear windows, which easily has plenty of glass area on the rear window to use a ceiling mounted mirror. I'm just concerned since the rear of the cab window area has a larger metal area vs glass area. In other words, would it be advisable to use a mirror that mounts to the windshield, as I could mount the mirror somewhat lower. I definitely prefer to mount the mirror which ever way the OEM did, but at the same time I don't want to have a restricted view due to the smaller rear window. I don't think it matters, but the truck is a 64 K1500 w/ factory 4wd.
