Does anyone know how to read the three numbers in back of the clock what format do they use? Day, month and year? Thank you

 

That's a Julian date - 180 would be June 30th, etc.

 

Thank you John

 

John,
I'm curious. Could that possibly be that the first two digits are the week and the last digit the year? I just looked at a clock with 384 ink-stamped on the back. It came out of a 65 built in late 64.
Regards,
Mike

 

Could be - the clock in my '67 is ink-stamped "165" and the car was built on June 8th, so it's obviously not the "born with" clock.

 

I have a similar situation, '65 built in Nov. "64. It has a 465 ink stamp. Yr. M. Day? M. Day. Yr. ?
