1/2 Dave:
According to the book Catalog of Chevy Truck ID Numbers 1946-1972, the first year for the tinted glass option was 1953. It was listed as E-Z Eye glass. It has a green tint to it. I have read in a couple of other places that 53 was the first year for that option. I have a 53, so in some of my other research I have run accross this info. However, it could be that the info I have read is not 100% correct. It seems that there were other exceptions back in the 50s.
I hope this helps.
