HELP can you decode this transmission for me?
would like to know what the first set of numbers is AND the second set of numbers mean
here are the numbers 2801544 3387017

2801544 is 67-68 426 Hemi.
The next four numbers is the 10,000 day calendar, last three are how many made that day.

Ok then I must be missing a number ????

No. that shows how few were made on any given day. Hemi's were in less than hundreds , all else in thousands. That shows it is clearly a Hemi Transmission.
