this is an FJ61, Gasoline Engine, the HJ60 and 61 dont come with ambulance doors.
Oh yes they do

The holes for both doors are usually predrilled into all 60 series as far as I know.
However the high roof and amby doors was not available in all countries but I have seen top of the range HJ61 with amby doors and high roof but not in oz
The "1" in 61 denotes that is a turbo diesel.No such thing as a FJ61
