PPG glass
 

looking for some help understanding Windscreen PPG glass #'s
re; 1969 Chevelle only. Shaded or clear.

Most of the windshield etchings are reverse image's . what I would like to know if you could look at your 69 Chevelle is what model # is listed.
It will be on the bottom line next to …..DOT18 M2x
I have info on 3 69's with shaded glass and the M2# is very light but looks like it could be M23. I also have one clear that is M21.
Another # could be M25 and that code according to CRG is for laminated windshield glass. http://www.camaros.org/glass.shtml#PPG
M20 and M27 are clear and shaded side and rear glass.


Thanks Mike

Recieved one PM confirming M23 on his car with tinted glass.
