As I recall the pulley on the AC compressor is smaller on the diesels because the diesels don't rev as much as the gas engines. Don't know if that is helpful or not.
As far as I know, the ac box, controls, etc, inside the cab is identical gas vs diesel at least up to around 2000. Biggest problem I have had is finding the AC box and fan, etc., for a LHD vehicle. There should be plenty of those parts in Australia if your truck is RHD. For what it is worth I'd go with OEM setup.
