The "Americanized interior" of the featured Falcon. The driver was relocated to the left to match U.S. specs, the LHD steering box was imported from the states (cheaper then importing the whole car).
The stock dash replaced by a simple formed panel. Note the lack of a clutch pedal, this vehicle was running an automatic when the photo was taken (there are at least four years of photos being shown, notice details like the whell color, writing on the windscreen). Other years it had a 4 speed.
And about that roll cage, almost unheard of in North America, it is ALUMINUM!
Reason: North America has iron ore deposits, OZ and NZ have aluminum ore deposits. Steel tubing is very $$$ Down Under.
Here are examples of the sheet metal used on the race car:
The basic XL series sedan provided the grille -
Found this on Photo Bucket, I was looking for a photo of the front of a stock XM but this caught my eye. No, the paint "colour" is NOT stock but the chrome side trim, grille surround, and scoop are. This is the body used on the NZ race car.
Photo of NZ FCA member Steve Frazer's XM undergoing a rebuild. Yep, they rot out in the same places as the North American cars.
In several of the photos post below there are images of an XP Falcon race car carrying the number 21. This is what the auto would have looked like in stock form; stock XP Falcon Futura shot by E. Selman in new Zealand. This is a 1966 and had about 24,000 miles showing when the photos were taken.
The XP's interior. Note that it has the upholstery of the North American Fairlane, a "Comet" dash, and insturment pod. But it is a Falcon.
Engine bays down under are arranged differently then in North America (the photo image is not reversed). This is the "Pursuit 170" engine which was replaced in 1967 with the "Bara" design. That engine still used the same block as North America but had a
cross flow head (carb on one side, exhaust on the other) with
detachable intake manifold. 
The back side of the XM and XP was a bit different then the North American Falcons. There seems to be photo evidence that this was the rear end treatment that would have been on the North American birds had "Lido" not order a total make over for the 64-65 Falcon.
