As for it being factory fitted. I'd like to see the Production Broadcast Sheet.

Never would a '74 built car get '73 dated windscreen or any other glass.

It is still a very grey science.
I have the broadcast sheet for this car, has A09 on it. Obviously Acacia Ridge didn't fit them at that time and relied upon the dealer to fit like the stripes.

The dating on glass goes by quarters. I think this one is 4th quarter 1973 which is OK for an earlier 1974 HQ especially low volume glass like side glass.
