The 1st day of April '69 was a TUESDAY. A car built any day that week, except Monday, would be an 04A car as far as the trim tag is concerned. If that car was built on Monday of the same week, it would have been an 03E (Monday the 31st of March would have been the 5th week of March). Also, it is my understanding that the trim tag date is the date that the car <span style="font-style: italic">began</span> assembly. It may have been completed the same day, but it could have been completed at a later date.

IMO, an 04C car would have had a start build date of 14-18 April.

I have always been curious about this, and it's great to see some discussion of it. But if this logic is correct my 06B should be 06C. Per the NCRS report, my June 13th build date would have been in the 3rd week of the month.
