Wow! That's amazing that Chrysler put the MDH of production on the FMVSS/CMVSS label because from what I know about that label it is only mandatory for the month and year at the top; hence the "ON THE DATE OF MANUFACTURE SHOWN ABOVE" and no reference to the lower right MDH info.

The month and year were only required because laws and regulation came into effect always on the first day of a month (i.e., Head restraints as of January 1, 1969, etc.) and not as of some random day during a month.

But still it's kind of a moving target because the bulletin states the MDH will be determined "at some point of production" but still that narrows it a lot because there would be very few cars that got started on say a Friday of a long holiday weekend and were finish on the following Tuesday. How many hours from Body-in-White until it rolled off the end of the production line.
