Yessir, that is indeed what I'm saying...however, whereas the Julian date on a '69 model 400thm transmission started on the calendar day January 1, 1968, and continued each and every day after, I think the Julian date on the trim tags is actual production days, and doesn't include weekends, Holidays, etc...

Maybe just a shot in the dark, but it explains why the numbers are sequential in regards to build date...
