Glass decode

[VegasCharger]

Hello I stumbled across this door glass in my shed and for the life of me I do not remember what it came out of. I took a pic of the etched codes in the glass. Anyone in here an expert in glass decoding?

I'm guessing 3rd gen B Body

Thanks in advance

EDIT: I guess I could add a pic of the entire glass.
