While I do have a W58 which aint for sale (for my Ute) an option for you to consider are the RWD hilux utes, W series from 2000 on in the diesels and the TGN16s have a RWD R150. Not sure about Vic but the wreckers in WA ask around $800 for them and you can fit the 154 gearsets which in the long term may cost you the same as a used R154 but give you the benefit of a practically brand new gearbox
