Something I have never paid attention to until doing some research on a friends car is glass date codes. I have owned my Trans am's for many years & I never thought to even check, nor did I really care to be honest.

Just curious what you guys might find.

I looked at two of my cars today.

This is what I found in the 1979 T/A
car was built February 1979
all glass dated XA (Feb 1979) no surprise, However the windshield is dated LC, march of 1976. How could that be? I keep in contact with the previous owner of the car & he claims its the original windshield. Could GM have really installed a windshield made 2.5 years earlier? seems unlikely, but also seems strange that someone would install a used windshield in the car. It looks like original urethane sealant, so I am just not sure, but I am confused.

My 78 is also a survivor car.

Built in March 22 1978
side windows at XJ (February 1978)
T-tops & back window LJ (March 1978)
Windshield XA (February 1979) uuhhh-oooo

(Damn, zero for two on what I thought were original windshields after all these years)

well i know that i have replaced my windshield several times because being able to see clearly means more to me than the date code.....but i'll go check tomorrow and see about the rear and side windows .......................

[jmc855]

FWIW, Sorry I know its been a while since I said I would look, been busy

so my rear window on white 79 hardtop is VJ Nov 78, Sides are TJ August 78 Car was built 3/79. Windshield is the 4th one since family owned her from 81 so no codes available.

79 S/E : Built 1/79. T-tops both CJ, as well as windshield (WOW!!!!) cant believe it could be original Dec 78.........Rear window and side windows are all VJ, Nov 78.

hope this helps!

On my Sept. 78 built '79 the windshield, door glass and tops are TJ (Aug.78) The back glass is AJ (Sept.78). All are Safety-Float?

[68ragtop]

Did yours really say safety float? The info I posted above I just cut & pasted from another website. I think my glass is all "safety flo-lite", but did have what appeared to be the same date code structure.

Ahh...edit: my are Flo-lite.

[68ragtop]

Not your fault.

I made the post & copied the info over. I was feeding you the verbiage.
