No Vin Stamp?

I'm not up on my slant stuff but I don't think that is the vin.

I think that stamp is

PT: Assembly Plant
225: Engine Size
R: Regular Fuel
2482: Assembly date on the Mopar 10,000 day calendar (Day 2482 is Tuesday, May 14, 1968 )
047: 47th assembled that day.


Meaning, someone put a used (or rebuilt), 1968, 225 in it at one time.
