All Cragars from day one have the month/day/year date of manufacture stamped on the inside of the steel rim-the part that is covered by the tire. Are the tires still on the wheels?

The bolt circle diameter is also molded in the recessed lug nut pocket on the backside of each wheel. 4.50 4.75 etc and there is no date code other than 1964 on the cast center section. The center section stayed the same from the mid 60's to late 70's (for direct bolt pattern wheels-not unilug)

Hope this helps.
