Not sure what gearbox you have, but give
QUAIFE a look. I installed one of their "Caterham" short throw shifters on the T9 five speed in our '64 4/4 and it's a vast improvement. The old shifter was very vague, sort of felt like a broomstick in a bucket of oatmeal. The Quaife unit has a very precise action. They may have dealers in Australia...
