Thanks to another member here, I believe I know what you're talking about;
for the Formula I believe you're meaning line five, the first three digits of the six digit number on the cowl tag;
480 = 48th build date;
According to Rocky's book the first date of 1973 model year builds was October 23rd;
With only taking off December 25th, that puts the year end at day #49 - so there must be a day or two that I am off...
either way, it was built right at the very beginning of the year.
