If it has the RPO code WU8 on the list or the door sticker, then Yes, I would say it should be. They all started as a Z28, ..., just like the Firehawks all started as Formula's/Trans Am's.
Have you seen the car firsthand?
Or thru photos only?
Make sure the door tag has the RPO code WU8 on it.
You also need to clarify to all of us as to what year it specifically is too, as the code may be different for the older cars, I'm not sure.
