'72 LT-1 AIR Pump Date Code

[Steve B.]

I'm confused on the date code of the AIR pump that came with my '72 LT-1. The stamping on the boss at the bottom of the pump has 066319 on it. There may be a "K" or "X" in front of the 0, but I can't tell for sure. It may even be a scratch on the boss because that stamp doesn't match the 066319 at all. What date is this?

Thanks in advance.

"If there is a first letter, it is for the assembly line. The next three numbers are Julian date; the fourth number is the last digit of the year; fifth number is the shift, and the last letter shows the model of the pump." From the 70-72 JG & TIM. 066319 works out to be the 66th day of 1973, 1st shift and ???? Should be a letter, not a numeral

That last letter is usually an S for Corvette applications.
