You probably also have the RPO codes "E7Z" & "E9Z" as well and a cable driven speedometer, correct?

Think if you look at the transmission tailshaft you'll see a standard speedometer cable outfit. The E5, E7, and E9Z build codes are just the factory parts that were or were not used on the speedometer drives in the various cars.

The speedo can be electric or cable-driven and still have these codes.
