I just picked up an NOS OEM mirror on Ebay with a date code of 6-DMI-7. The mirror is rectangular but as has a 67 date code. I thought that all of the 67 mirrors were round so what's up with a 1967 rectangular mirror?
I'm not building a correct show car so I don't really care if the date matches my car but I am curious. I bought this mirror because I don't like the quality of the aftermarket mirror that I bought a while back, it won't even adjust to a position that I can use it. Can anyone say why a rectangular mirror would have a 67 date code?
