Tags were pretty basic pre-'66, not a lot of info. You can get a copy of the IBM build card from Chrysler Historical, that will give you more info & there could/should be a broadcast sheet inside the car waiting to be found.

Info on tags varied by plant, is your car from the Newark, DE assembly plant? VIN would start - 3116xxxxxx.

Does it appear to be originally 4bbl? Got pics of the car?
