Newbie Needs some help with a 69 Z 28

Probably unrelated, the 6-8 tach went into production late January. However it was phased-in, cars through March were built with either.

The 6500/8000 tach shows up October '69, phased-in again.

I have a question William.  Since it may possibly be related to the required tach option you posted.

When the required tach option went into affect (I'm guessing Feb onward??) would this also be the same time frame they changed the tach to the 6-8 configuration??  Or was that phased in a little later?
