LT1 balancer date, 302 date
 

I have an LT1 balancer dated J 0 F. I am guessing:

J = 10th day of the month

0 = 1970

F = June

Anyone know FOR SURE if that is the correct format?

Also have a 7708 balancer dated f 16 S (or 8) so maybe the first letter is the month? Were 69 and 70 balancers dated with the same format?

Thanks in advance.
