1973 Dart Sport air code?

I was thinking of the tinted glass myself, I had a 1975 Dart Sport many years ago and I installed all tinted glass from a A/C car.

this is what i found digging around on the interweb.

It would not be a 100% guarantee it was an A/C car with tinded windows.
if you look at the attached paperwork you will notice option G21.
- Clear Glass.

Either way, even without H51 and/or G21 on the fender tag it doesn't really bother me as I have a car with factory air I can use as a donor. it is a six cylinder though.

thx everyone.
