PPG Glass Date Codes?

[Mark_C]

I don't think that is correct:

My glass (04L Pace car) are coded as follows:

Drivers door: 26-29
Drivers Quarter: 27-29
Passenger Door: 16-29
Passenger Quarter: 27-29

My passenger door has no DOT codes on it which would indicate it was made before 1/1/69 since glass had to carry a DOT code after that date.

A wild guess would be that the first 2 numbers are a week code based on the production year. The first week of August would be 1, January 1, 1969 would be 23. The second one could be the assembly plant if there are 29 of them, or it could be plant no. 2 in year engine in a 9.

The common factor here seems to be the last digit.Joe G has a 69 Chevelle, his PPG Glass codes end in 9. Mark C has a 69 Camaro, his codes end in 9 also. I have a late 70 Chevelle conv. my PPG Glass codes end in 0. Doesn't it make sense that the last digit could be the year it was made?.........Kevin

The first two numbers are the PLANT CODE...last two numbers are the date code...ie., 26-95 Plant code is 26 and 9 = Sept. and 5 = 1965.

ALL PPG glass plant codes are not known at this time...atleast by me anyway.

SORRY GUYS---WROTE down day/month---should have been month/year according to PPG cust service--copied down the wrong message---haven't check this site in a while [img]/ubbthreads/images/graemlins/confused.gif[/img]

27-29--FIRST SET 27 =plant # SECOND SET 29 = month/year This is what cust service said ---you can call them and maybe get a better answer.--I am now in the process of grinding off all the date codes on my windows [img]/ubbthreads/images/graemlins/tongue.gif[/img]----------- [img]/ubbthreads/images/graemlins/beers.gif[/img]

musclecarkid;

I am just back from the Nova Nationals where I saw a one owner 71 Nova with 2 original PPG vent glasses and the rest LOF. I came to the same conclusion. Most of the LOF glass dated July 70 so 26-60 decoding as June 70 would work. I had though that 26 would have been day of the month, but based on above it looks like plant code.
