How does the jack assy date correspond to the cars SPD?

In other words my Duster has a 10/14/1970 SPD, what date jack would I look for?



I have 14 E bodies, and all of them that have original jacks, have them coded the same month as the month that the SPD of the car is, unless it is made in the first three days of the month(then the jack is from the previous month). The one you should be looking for is 0 K for Oct. 1970. I am sure there are exceptions to this, but this is what I have found with mine.
