The '37 Chevy didn't have a modern VIN. It had a model designator and a serial number. The '37 Master was code GB, and the plate was under the hood on the right (passenger) side of the cowl panel.

The number you have on the title doesn't seem to make sense for a '37 - other than the "GB" code. Chevrolet didn't use prefixes then, and they didn't make 700,000 of any model.

Also, what you have is not the engine number. The '37 engines had only a serial number - no prefix.

I could be wrong, but I don't think so.

Since you have a valid title, how about making a plate that matches the title?
