I'm not sure if this answers your question, but the first thing I did was buy the rims 10x17's and 8x17's and asked for as much dish as possible to look like the hot-wires you would see back in the day without going crazy.
Then I sat them under the car where I thought they should sit, and measured from rim to rim.
Rodtech in Adelaide did the rest with the diff.
Just FYI (and it wasn't my question in the first place) but wheels like that are generally just done in one casting per 'size'. The offset range is just a case of machining different amounts of meat off the hub mating face (normally you'd have about an inch range of offset to choose from) so the dish is not affected at all.
I would IMAGINE that any 17x10" Repro Hotwire from that company has exactly the same amount of dish. And consequently your reply doesn't really answer his question, haha.
