    C-2 Outside RR View Glass Code

    Here's one that may create some controversy. Is it possible that an outside rear view mirror glass dated 9DMI5 (sept.1965) be correct original on a 1967 car, built 3/21/67? I have owned the car for 23 years and it looks like an original mirror. Possibly mirror glasses were stamped/cut by the thousands and used well into subsequent model years? I realize there is a "6 month" rule, but, for example, we have seen in years past(per The Restorer), that some components, namely certain eng. blocks could be older and still be correct.Any thoughts?

    The judge will probably deduct 1 point.

      Don,

      The glass in one of the vent windows in my July 66 build date car has a Sept 65 date code. I believe the glass is original, but I think as Don suggests, it will result in a points deduct and the chances are zero that I could argue out of the deduct. Also, one of my aluminum valve covers has the casting flaw and one doesn't, whereas the JG says both should have the flaw. Again, I think both covers are original, since I've talked to all previous owners about this specific issue, but again, I think that convinging a judge that the non-flawed cover is original is a lost battle. If the mirror date is a 1 point deduct, I think you'd be better off taking the deduct than arguing a lost cause with the judges and perhaps annoying them with an argument you're simply not going to win.

        Don - Everything is possible, but some things are less likely to have occurred. One thing to consider but not clear from your post is the 'bow tie' logo on the mirror housing.

        Does the mirror have a "bow tie" on it? TIM&JG indicates after #10,500 "bow tie" was not used.

          Pete,

          Mirror is plain, w/o "bowtie" as car is SN 141XX. I remain convinced that this is the original mirror. More research is needed in the area of non-conforming dates on parts. It is virtually impossible to prove it was "as built,as delivered" using a single incidence. Perhaps a survey is in order? No matter, I believe it to be correct.Thanks for your interest.
          PS- How about others out there with pre-dated mirror glass? It only takes a minute to check. Aren't you curious???

            Don - I'm with you. Stick to your "guns" if you have every reason to believe it's the original mirror. Changing to conform to the current thinking or information robs us all of what the real situation was. If there are other cases, hopefully, others will "step up" if they have observed the same or similar situation(s). These kind of things help everyone understand that a lot of things happened during production and help expand our knowledge of what 'really" went on 30 to 40 years ago. We've learned a lot by someone pointing out the tip of the iceberg. Good luck, Pete

                Frankly, I think that it is next to impossible for this to be correct. Yours would have most likely had a 1DMI7. That is the most common one around that time frame.

                  Don,
                  As a data point, my March '65 Roadster has an outside mirror coded 1DMI-5. I guess from your post that this means the mirror is Jan. '65? Two months before the car's birthday.

                  Hope this helps.
                  Gene

                    Re: C-2 Outside RR View Glass Code

                    OK, let's approach this from another angle. Did GM service replacement or NOS outside mirrors come with "DMI" dated glass?? Next and final question- do repro mirrors (Zip, Paragon,etc.) come with "DMI" dated glass? I might add that my mirror has the correct snap ring, no bowtie and has been on the car for the 23 years I've owned it.. If repro or service replacements came DMI date coded, I guess I'll accept that my mirror is very likely a replacement and end it. Thanks to all for your help.

                      Don: Yes repo mirror glass comes with DMI dating. Paragon sells the dated replacement mirror glass for both the inside as well as the outside mirrors. In fact I just purchased a replacement for my '63 outside bowtie mirror at Carlisle because the silver backing on mine was a little spotty. Len

                        Don - The old GM replacement OSRV mirrors with the correct configuration, i.e. ring to hold the mirror glass, did in fact come with DMI date coded glass. In addition, there was also a GM mirror glass replacement kit and the one I saw had the DMI date coded mirror glass. Pete
