Question Door glass codes on my 69 Camaro

Hi all,
Can I get some of feedback on My 69 Camaro glass codes, please? I have an early build 69 Camaro 09B (2nd week of September 1968). The quarter windows and back glass all appear to match with the same date code, type, etc. which is UX (July 1968) but the door glass is different. I actually have what I believe is a 67 or 68 Camaro door glass currently installed because the date codes are CZ and YZ and have "Astro Ventilation" etched on the insides of the glass so it's readable from the outside. I do have two extra door glass in my garage. My windshield was cracked when I bought the car so I chucked it and never thought to check the date code. Since my car was built on 09B of 68, does it seem correct that my date codes would be UX (July 68)?
Would the door glass have to match the same as the others with the UX code and the M75? The codes appear to show my quarters and back glass as tinted, so would my door glass have been tinted too originally?

I will attach the pics of the codes and the Astro ventilation.
Below is the list of codes from all of my glass.....

IX= June 1968

Passenger Window (Spare)

UX= July 1968

Drivers Quarter Window

Re: Door glass codes on my 69 Camaro

True. As the Astro ventilation windows are coded in the latter part of 67, I can only assume someone replaced the original glass with 68 glass. Otherwise, it would have had to be a rare occasion where they had been building the car and happened to have that glass lying around a year later but I think that would be a stretch. I haven't heard of any other 69's that came with this on the windows. However, if there is some possibility of it being original to the car then I want to know. I want all my glass to be coded correctly and of course I prefer keeping the original glass if I can.

Re: Door glass codes on my 69 Camaro

My 02A Camaro has a Jan 69 glass on one side and a Dec 68 on the other and they are original to the car.
Hope this helps.

Re: Door glass codes on my 69 Camaro

I would say it is impossible to get two early 68 Astro ventilation door lites in a 69 a year later. One door lite would be highly unlikely but not impossible.
Glass is not produced as a matched set. The furnace would be set to run drivers doors and they would be packed in racks for shipping. The furnace would change-over and run the passenger door lite. These would be in separate aisles different shifts come and go. The furnace would change over and run rear quarter lites as a double line. Passenger on one side and driver on the other side. Packed into separate racks and stacked in different aisles. Rossford had 5 tempering furnaces so more than likely the back-lite was from a different furnace. The windshield was produced on a gravity sink furnace in molds and then had to go to the lamination line after before being packed for shipping. A lot of glass and a lot of other models beings produced.
So the impossibility of two Astro ventilation door lites going into repair in separate racks early in 68 production and being repaired and ending up in separate shipping racks in early 69 production and meeting up together and installed in the same car is just not going to happen.
I can add being that early in 69 production your original door lites whatever happened to them would have had a September 68 or August 68 date code both would be correct. As I have stated here before the later in the model year you get the less likely all your glass date codes match.
The one thing we do on most windshields nowadays is along with the month code we add a dot for which run of the month that part has been run. Just a quality tracking thing when you are producing 40 thousand of the same part over 4 different production runs a month.

Hope this helps

Re: Door glass codes on my 69 Camaro

I thought it was impossible too....having those in my 69 1 year after. I wonder what the value of the two door glass that have the Astro on them would be. Do you know how to tell if it's real? When I run my fingernail over it, it feels like each letter is raised. Kind of like a business card with raised lettering would feel.
What about my quarters and back-lite dates? They all have the same date codes and Type. Are you saying that they should or shouldn't have the same date codes?

Re: Door glass codes on my 69 Camaro

The rear quarters and back lite being that early in the model year should be the same or even from august. No Idea if the Astro Ventilation glass is real or what its worth.
