Thanks for your help guys.
It was an honest mistake by the guy who supplied the gearbox to me and he is tracking down another toploader for me.
The real mystery is how this gearbox ended up in Australia. I cannot think of any Ford sold in Australia that had a floor shift 3 speed with overdrive fitted to it. Unless some Broncos where fitted with this gearbox, it looks like it was probably in a car that was privately imported.
