Anyone know of a T5 conversion done in Australia?

[Datso]

Im looking at AlfaBB and theres a chap who has done the conversion to a t5 box.

The close ratio sets and rebuild kits for this box are the cheapest in the world.
The T5 boxes are also compact and available with endless combinations of
shifter positions if the Falcon or ford arrangement is too long.

This would save me find a good 105 box that will probably live a short life in a
high revving engine with hopefully 190hp ate.
