1972 FORD FALCON XY 4x4 UTE. Replica or Genuine?

I have an opportunity to purchase a 1972 FORD FALCON XY 4x4 UTE. How can I ensure that it is a genuine factory build from Brisbane and not just a replica or mock up? The gentleman who owns it has no idea about the vehicle at all.

I suppose the vin number would help

It's written on the vin number as 4x. I actually own one also and would be happy to have a chat to you about them also. What's your phone number?
