Damn! I LOVE em!
I ran Peep Mirrors on my 67 (and now my 72).
Never had a problem with them, except in the very beggining,
I had to train myself to look "UP" at it, instead of down as with a regular mounted side mirror.
Now granted, I don't Tow, Haul or have a Camper, but I am not aware of any "Blind Spots".
I run one on the Drtivers Side only,
and have never had a problem with Law Enforcment or the CHP.
I lived in Nor Cal and am now down in SO Cal, without any problems.
I have no vibration on my Peep Mirror, whatsoever.
GO FOR IT!
