Buck351, keep in mind the scheduled production date on the buildsheet and fender tag is just that, the car could have been built before that date, on that date, or after.
The engine should have a casting date, I forget which side, but just below the oil pan, and the assembly date below the distributor.

The casting date could be months prior to the assembly date, the assembly date should be very close to the actual shipping date.

The actual shipping date will be on the IBM build card and in the letter from Chrysler.

When I got mine, I discovered that my car was actually shipped a few days after the engine assembly date, not over a week after as the fender tag stated.
