I’m trying to order new date coded glass for my 1973 Mach1. My car is a non-air conditioned and came with clear door and quarter glass. I know the “Carlite” etching logo changed sometime in late 1972. My car was built in February 1973 and I believe would have later design. I don’t have any of the original side glass to reference so I would like to see some photos of the etching on 1973 clear side glass. Please help!
