Sorry, I came in late on this discussion, but I got the impression it was being implied the 4080 car was campaigned in the '75 & '76 ARC championships. But it would appear neither Dunkerton or any of the other Zed front runners were using the 4080 car which gives credence to the car being returned to Japan.
Actually, period photos do indeed appear to show Dunkerton using an LHD rally car wearing the 'TKS 33 SU 4080' works carnet license plate in both '75 and '76...
Edit: For Example:
...which by all accounts seems to be from the 1976 Lutwyche Village Warana Rally in Queensland.
