Yup, there were a standard option from the second model onwards. They don't often come up for sale second hand though. I should point out, just like the rest of the car, they tend to be asymmetrical, that is, one is bigger than the other (that's what she said! lol). That said however, one of the Eureka club members made molds, and improved upon the design. Originally their is just lip on the inside of the intake that you can use to bolt/screw/tape it to the body work. What he's done is made it into a two part design (I think I remember that correctly). There's a base plate that will fit into the 'scolloped' intake in the body tub, and the top half which you can fasten to the base plate. That means that the new air intake will fit into the existing intake, which you can then secure through the body work inside the original air intake, or even by using something like a section of pvc pipe and securing that to the new air intake so you don't have to drill/screw through the body tub. Also, The fit to the top of the body tub is much cleaner/smoother, and would help channel more air into the body tub to be ducted to where ever you want/need it.
Another thing to point out, shipping between Oz and the rest of the Known World isn't cheap. As a (poor) example, I'm getting a new fuel sender shipped out from the US of A, and that set me back $27 USD for the shipping alone.
If interested, I can try get in contact with the member who made the redesigned 'elephant ear' intakes. He doesn't tend to post a lot on the forums, and so it can take a while to get a set of intakes made up.
I act as the International contact point for the car club anyway, so I don't mind doing the 'footwork' on this side of the pond.
