I looked through the library's car glass date code info and unfortunately remote rear view mirror glass date codes were overlooked. The date code on the mirror in question reads 2-DMI-7 normally I would read this as month first then year, 2- February and 7- being 67 since this came from a 67 built (4/28/67) car. The reason Im asking about this is the person I talked to about this interpreted the date as year first and month second, 2-72 and 7-july. I hope Im right thanks Paul. ;)

I believe it is a Feb 67 date code . I know some restorers that will take a correct dated glass and transfer it to another body.

I have done it, not easy but do able. Worth the effort to have a correct date coded glass.

Would not confirm. Why?
Because I have a mirror 4 DMI 3. Would mean April 63 according to above. But can't be. The mirror has the shape of a 67/68 car.
Even year first, month second doesn't make sense to me.
Imho there must be another specification behind.
Thx Ralf

I'm NOT an expert on decoding glass or mirror dates but it seems that the "decade" of production of these items is not coded into the date code so if your "decoding process" is correct, it could be possible the one you are looking at is a Service Replacement part.
-
+1 Service replacement parts were produced in to the 90s

In other words your example could be 73,83 or 93 . Not to say a NOS piece with a 7 or 8 couldn't be 78,88 etc. The code with a relevant number is better then one with a no way it's relevant number. I mentioned the process to switch mirror glass as a alternate way to get a date coded mirror so those looking don't get too frustrated. I would like to say that sometime people get too evolved with the nuance details and disregard the big picture or more visible aspects.

I just obtained a 67 DS mirror (has C7AB17743B mirror base and 67 style adjusting knob) with 6JC7 date code
Decipher the code please? So far, I am confused with what was shared earlier in this thread. (want to wrap my head around mirror codes better)

FWIW; the OE dual racing mirrors on my 69 are date stamped 8JC8 and decode; 1968 September. The C8 is the prefix to the engineering number. Brian

Following the decipher you describe, it seems odd that the numbers on the several "JC" mirrors I have seen so far are all SEPTEMBER dates (or is it?). If others concur, this code on my mirror would be 1966, September C7 engineering. This fits well to my need but I have t wonder why there are other 1967 examples like 1 DM1 7 OR 4 DM1 3
I was beginning to think there were two suppliers. JC and DM
Maybe too complicated to understand at this point in time...

So, going along these lines of discussion and using a date coded glass removed from an original, I noticed the "etching" of the code, at least in the example I am working with, is etched into the "silvering" layer, not on the outer surface. (there was previous conversations on "etching" a code ONTO a replacement glass, similar to what is done on windshields).
I will upload a picture of the etching with a few "backlight shots" to show what I am trying to write out.

Very old thread but I'm trying to get a handle on the etching on my side door mirrors.
My driver side is etched 12-DMI-7
My passenger door mirror which I have no documentation confirming when it was installed is 6-DMI-7
The base my passenger mirror is C7AB17743 A. Below that is 15 15 53 1
What do these numbers tell you?

I took off my driver side mirror. It put up a good fight because the rear screw spun in place since the insert was loose. After taking off the inside door panel and with a struggle, I was able to get the rear nut out. I'll have to determine how to secure the rear insert.
But my point is the base of the driver side mirror is marked the exact same as the passenger side. C7AB17743 A and below that 15 15 53 1
Does that mean they are from the same batch of mirrors of were all mirrors for multiple years marked the same?

ran into the non sticking nutsert problem while installing a visor over the windshield on my truck. used a small dab of j-b weld to hold it still. i did not use the quick type. worked quite well.

Mirrors can be identified by understanding a few simple rules. If the mirror is marked with "DMI" it was supplied to Ford by "Donnelly Mirror INC". The first number identified the month produced. The DMI is Donnelly company, and the second number gives the year. There was a second supplier to Ford named "AJAX" and the mirrors they supplied were coded in the following way: First symbol will be a letter of the alphabet indicating the MONTH (January would be indicated by "A" . "B" would indicate February and so on) The letters JX will follow the month, and the last two numbers will indicate the year. (67) so you would see a mark such as A-JX-68 for a mirror coded January of 1968 and manufactured by Ajax INC. Hope this in some way helps you identify at least two sources of outside mirrors and the manufacturers marks and date coding

great info there murf! never knew that.......always learn something here!

Thank you also for this info. This is fantastic.
My personal question relating to my car then is if I have two mirrors, 12-DMI-7 and 6-DMI-7, of which 12-DMI-7 was found on the driver side, which could have been switched from one side of the car to the other when it was repainted, was the passenger side mirror added possibly when the car was purchased to make it a dealer installed option and that would be ok for MCA driven standards or will it always be a deduction unless it's gone, no matter?

The date codes are not considered for a deduction in the driven class.
