Passenger side air vent from Oz?

I have an original heater delete '66 Valiant 100 that is missing the passenger side fresh air vent assy.,the dealer installed a '63 style underdash heater when it was a new car,so the original vent probably got tossed.I am wondering if the RHD cars from down under would use this same part? Can any members confirm this? Any members from Oz out there? If so,maybe a photo of what an original RHD car would have used?
I just placed an ad in the classifieds looking for one of these,but I've never seen one for sale anywhere,I'm sure they aren't real common.Thanks for any info! Rod.
