The only thing I would question is the base. If you look on the Python site here in Melbourne:

...you'll see that his billet adapter looks very similar to the 2" cap base from Finishline:

Compare that to the open base cap from Finishline and you'll see how it doesn't taper in towards the bottom.
Can anyone verify which base is the correct one for Australian pumps?
