Glass codes

[Challenger6pak]

I used to know how to decode them.  I know it is real simple.  Will someone refresh my memory of how to do it?  Thanks,
Tod

The sales codes like G11, G15, etc?

Or the actual glass etching?

I just bought some dated coded stuff from ECS
This was for a 70 challenger built 9/1969

Windshield has  AS1  for laminated glass
 Rear glass       AS2  for tempered
The next number is for the date of manufacture  eg  99 = sept 1969    69 = april 1969     123= dec 1973
The M44 is for tinted on my windshield  and M56 for tint on the rear glass

oops made a typo on that last post 69=june 1969  49= April 1969

My computer died. I had to wipe it clean and reload it.  Sorry for the delay.  Thanks for the responses.  Barry I need to decode the codes on 20 door glasses that I have.  I am planning a move from my home and am not going to move all this stuff.  I also have quarter glass and rear glass to decode. I am looking to decode the etching.  Thanks.

Anyone have any idea of how to decode these etchings?  I would like to get this glass to people who need it instead of it just sitting in storage bins.  Thanks.

If anyone finds out how to do the decoding please let me know.  If I learn how to do it again I will post it.
Thanks.

I asked Roger Gibson and he cleared up how to do it.

The date code is on the second row up from the bottom last numbers.  Bottom row should be a DOT#.  The dates read;  109 October 69),  31  March 71, ect.
