dating Side post battery cables

[BULLITT65]

So this came up recently while I was looking for an original side post battery cable (6297651 AV), the date on the back side of the terminal is (9B).
I looked at my positive cable and it is also dated (9B). I asked Gary what date is on the back of his negative cable of his October Z and he reported (12B)

I am curious if any other owners have there original side post cables and what the dates are on the back side of the terminal connection, and if anyone knows how to de-code these.

Thanks

I doubt it's a date, probably a mold number.

Austin,  I hate to correct you, but my Z28 was a September 18 production... 

PS.  I would also concur with Kurt... that the code is likely a mold code rather than a date code.

sorry about that Gary.

Wonder why they would have a different mold ?

GM used multiple molds for essentially every part they made...  it was a necessity.

Austin:  You have the opportunity to start a 'data collection' for these codes on original battery cables, and when you have sufficient data, it will probably be obvious what the code is for (a date or a mold #)...or ??

Well if I had that many data points I probably would have located a cable for my car by now...

I have seen about 6 of these cables since I began looking, but I just learned of the number on the back side.

I get your point though.

Cavity numbers - typically used when there is a problem so it can be isolated to a certain cavity in the mold...

[BULLITT65]

Sticking with the line of reasoning then, if my 08C car has a 9B on the cable, and if Garys 09C has a 12B, would that indicate the somewhere between the production of my car and Garys that they made a new improved casting of that side post cable?

[KurtS]

No. The mold looks like an egg carton with rows of these cavities. Each cavity is numbered. When each mold is filled, all cavities are filled.  If it's 12 cavity mold, 12 parts made at once.  They had to make them for all the plants - that's a lot.

Not 100% positive in this case as I haven't seen the tool, but many molds like this that essentially overmold plastic over metal are "shuttle" style molds that have two "B" halves and one "A" half.  This way, operators can be loading the metal parts in place while the overmold operation occurs in the press.  This is much more efficient.  This may account for the letter designation.
