Is there a deduction on what glass you use on a 38 Cabriolet? I'm trying to build s 1000 point car and don't want to use the wrong glass. I don't think they used tinted glass but did they use safety glass?

I do not know if the glass was tinted

I do know that all of the windows in Chevy’s in that era were what we call “safety glass”. That means it was 2 layers of glass with a clear flexible film between the layers. That film discolors over time. Also the bond between it and the glass will fail. That creates the bubbles you see in the older original glass.

An advantage is that this type glass can be cut to size and shape locally.

I do not know when Chevrolet started using single layer tempered glass. The advantage is that it is stronger and lighter. One disadvantage is that it must be cut to size and shape before it is tempered. And when it breaks you will be cleaning up pieces forever!

The date such as 6-38 was combined with the LOF ID in a corner of the glass
Fisher used saftey plate glass all around and not satey sheet glass.
Tempered glass wasnot used for windshields or side windows.

some closed cars used it in the back glass.

I never saw VCCA look for date codes, etc.

Chevrolet first used tinted glass in 1952

My '39 had dated glass

I still have the OEM glass in my 38 except for the windshield which broke when trying to remove it for paint. All the glass in the car is laminated except for the back glass. We removed all the glass for body work and paint. I don't know if the back glass is tempered or not but it is not laminated and is a tad thicker than the laminated in the rest of the car.

Yes, some 1938 and 1939 cars had tempered glass in the back window and was not dated etc.
The 1940 and up all had tempered in the rear because it was curved glass. It was used im the side windows in the 1960s but not legal for windsields because it does not chip but shatters into a million pieces.
I believe in Eroupe it was used i windshilds.
