Rochester 2g tri power

Can anyone provide some info on where I can source a set of Rochester 2G,s set up for Tri power, progressive linkage, going on a 283 chev.?
I have an early edelbrock manifold so only looking for carby,s to suit.
I,m in South Australia so any Aussie Hambers feel free to send me some info.
Thanks
