Re: 50 years ago I was given this USAF 54 3100

The repro original style rear view mirror has been giving me neck cramps. Its either too high or i have shrunk in the past 5 decades. Sadly i think it is the latter. After some quick fabbing i came up with a 2" x 1/2 extension and drilled 4 5/16' equally spaced holes in it. After some tries I used the top and bottom holes Drops mirror about 1.5" inches and no more cramps. Can easily see way back now. The extra length did cause some vibration issues. Split a 1" rubber firewall grommet and placed behind the mount and re tightened screws. You can just see the grommet in last pic. Damps it pretty good and hardly shows. If you have one of these i found the stud thread is roughly 1/4 x24 NF. Not having any handy I re threaded an 1/4 x28NF Allen head and the extra attaching nut. If you having same problem this is a cheap and easy fix.
