Speedometer gear box

Does anyone know if a 1969 - 9561 COPO 4 speed - 4.10 gear ratio came with a gear box for the speedometer as factory equipment?

My '69 Z/28 was built with a 4.10, and it doesn't use the adapter - just has a 25-tooth orange speedo gear; however, the shorter 14" tires on a COPO may have required it.

Depends on which trans was installed.

Thanks! The car does have 14" tires.

The transmission is a M22. 

I want to make sure I get the correct pieces while assembling this car.  During my research, I have found contradicting info on this.
