I would contact the company directly and get most of the specifications from them, if not all, that would be needed for Austrailian registration. I would forward them the paperwork that you need to fill out/satisfy. From what I have heard can be a brutal registration process down under. I think CCP is a big enough company that they are aware (or if not should be made aware) of the problems of using their products and might assist you with the registration paper work to help them get a better footing in the Australian market.
I found this article with pictures
HERE Of course it only stated Chevies and a 1/2 ton Ford.
Please keep us informed as to what you find out from CCP, I plan to add power steering to my big 'Bolt but the plan is not so straight forward nor would be easy (read more time consuming for the engineer) to prepare documents for.
One last thought, if CCP says it's steering box has too little force for a 2 ton, ask if they could add a hydro assit cylinder like the rockcrawlers use for their HUGE tires.
