Superbird back glass

I have a superbird with a rear glass date code of 99m 9-69 my windshield also has 99m date code. I am looking to buy a new rear glass but have found 2 vendors, one has a date code of 119G 11-69, the other is AMD and I do not know what date code they use. I have been told all superbird rear glass is date coded the same. My question is for those with known original cars what are your date codes, before I spend my money and make phone calls. My glass looks as if it has never been changed, BUT who knows. Here is what my car has.


SAFEGUARD
SOLID TEMPERED
SAFTYGLASS
PENTASTAR P 99M
P M1 3 AS2

I will try to check mine this evening, when I get home.

AMD says their glass is 99M.

Mine has 99M, also.

Thanks for the quick response.

I have one in my shop now with the same marking.

Dave, is 99M the only date code for original cars.
