Restoration / Re: 1967 Door MIRRORS; help please?

Seems unlikely to me that a June 1966 manufactured mirror would be without the bowtie. All 66 Chevelle mirrors (which is the same mirror except with the bowtie) had the bowtie, and those cars were being produced through the end of July, while Camaros were not to come out until late August.
Remember that the 67 style non-bowtie mirror was still made by the OEM mfr. well into the 90's. The Chevy Luv trucks of the mid 70's also used them with the same bracket and gasket. Your 6-DMI-6 mirror is most likely a June 1976 manufactured mirror that was installed as a replacement some time after that date. Donnelly Mirror Inc. (DMI) was still marking them with the same m-DMI-y format at that time.
They changed their name to Donnelly Corporation of America in 1984, and at some point after that they changed the mirror marking to m-DCA-y. Then later it changed to m-DCA(R)-y (with the (R) being the trademark emblem). Somewhere I have a list that pins down the change dates pretty good, but I cannot find it now!
