Back in those days the side windows were laminated safety glass. You can go to any glass shop and they can cut one for you. They can show you examples of various tints. If you wanted to have tempered glass, they can also cut that for you and send it out to be tempered. As for the logo, I'm sure they can provide the glass without any and you could find someone to etch what you want. That would be a little more trouble but it depends on how accurate you feel you need to be.
