Etched Window Glass
Short answer: The “bird” logo on some 1968 front side glass is a special factory glass, but why some cars got it remains a mystery — a multi-year Registry survey found it across too many configurations to establish a pattern.
These common theories are NOT true:
- Only cars built before 5-1-68
- Only A/C and/or power-window cars
- Only early-production cars
- Only tinted-glass cars
Documented original bird-glass cars include 400s and 350s, with and without A/C, with and without the Custom trim option, coupes and convertibles, clear and tinted glass, automatics and 4-speeds. (An earlier observation that they were all 400s was later contradicted by 350 examples.) The feature appears on early 1968 cars — the latest known build is around the first week of March 1968 — and may have been dropped for production cost. (See also the “Etched Bird Glass” FAQ on what the marking actually is.)

My brother has 1968 firebird with the etched windows. Where do I send the info on it for the research?
I recently purchased a 1968 Firebird convertible that was disassembled and in the early stages of restoration and as I have been learning more about my Firebird, I read that factory AC cars typically came with tinted windows. So I decided to checked the glass in my doors and quarters to verify that my glass was tinted. What I found was that only the drivers (LH) side was tinted and, to my surprise, I found that other glass was clear and that my RH side glass was clear with the Firebird emblem on it. Assuming that the RH side is original and the LH side had been replaced, I wanted to share as much info that I can on my car to add to the research. I do not know all the details on what model Firebird (350, 400, etc.) my car was, by this is what I can share:
Date Code: 11C
ST Code: 68-22667 LOR
Body Code: 2062
TR Code: 259 (Black Deluxe interior)
Paint Code: G-2 (April Gold – Black Top)
VIN: 223678U122107
My dad found a passenger window at a junkyard for his 69 camaro and when he cleaned it found the bird etched in it. Needless to say he had to find another glass but still has it sitting around.
I recently purchased a 1968 Firebird Convertible that is a 350, auto, roll-up windows and it has the etched bird on the windows. It is a 223678U vin. Does this add value to the car or is it just cool 🙂
Cool factor.
this topic has come up again on Facebook. was there any more info ever found out about the Bird glass? from what I remember and have read on here over the years is that from Oct to Dec 1967 the Bird glass was in production and installed on Firebirds from the second to the third week of Nov 1967 to second to third week of Jan 1968. I there any more info on this matter.. any investigations going on now is flawed as in the last 30+yrs people have been installing the Bird glass in their cars
Hello, wanted to comment on the etched glass. I bought a 67 firebird from a fella 8 years ago in Paso Robles. The two vent windows each have etched birds on them. They also have the names of Diane under the bird on the drivers side and the name Mark under the bird on the passenger side. If you would like more info such as vin and such Id be glad to respond. Wish the privacy act to research who used to own the car before didn’t exist. Would be cool to know how many owners this car had.
