Along the bead and stamp into the tire, not raised. I believe it is just a number. The week and last number would be the year. I'm sure the tires are way outdated. I would buy new tires and save the old ones until you can find more history of the car. Nice project you have here.
Thank you. I plan on getting DOT legal for the back. I will definitely save the old ones. We will know a lot more next week when we take the engine out.
