I got my hand brake cables done at a place at coppers plains... (Not 100% that was the suburb)
They're just around the corner from the Ulans bike club house...
They make trailers so I guess you could just try a company near you that makes trailers....
You will need to have all the right fittings for your outer section of the cable though..
As for your diff.......
They do come from the factory in the size you mentioned....
Maybe try and reference what year model had what lenght diff and you should be able to get the right seal...
(i didn't know the seals were differnet from hiace to hilux, or between years.)
Your other option is to get to seals off and chase up the code on them. Same as you would for random berings.
In your pics it looks like you have an early model diff as most of the later models step up in size on the axle tube....
Thats for hiux though....Have no idea what a hiace housing looks like....
Hope this helps..
