Try here for the Normative Practices in First-Generation Camaro Window Glass from camaros.org as a start. Not much on PPG codes, but explains everything else.

AS-2 = "The stronger, 1/4-inch thick, AS-2 tempered glass was normally used in Camaro doors"

27-30 = What you need to know [img]/ubbthreads/images/graemlins/dunno.gif[/img]

DOT 18 = Manufacturer code PPG number is "DOT 18"

M78 = "model numbers to each type of auto glass, and each type received a different model number mark as required by ANSI Z26" M78 is proabably side door or quarter.
