I've bought a new cable from Mustang Motorsport in Ferntree Gully, Melbourne. about $200. I ended up not needing it and returned it about 2-3 years ago, so they have them/can get them. I had mine repaired for $18 (the end broke off!) and it's as good as new. They're REALLY heavy, there's no getting away from that...
Also, things like disc brakes - get the from the US. For instance - Ford pads for the front only, from your lcoal ford dealer - $885 fitted. Set of 4 vented discs and pads - $300 in the US. You know it makes sense...
