Not really a good reason to sell up dude - especially if you are in Perth
There is a bucket load of parts around, you just have to know where to look. I can give you 3 places off the top of my head that currently have half cuts. I have only had mine since december and I have had to track down a few bits and pieces for mine and for other peoples, everything from simple stuff like cargo barriers right up to major stuff like driveshafts and entire auto gearboxes and the most it has taken me to find them was 1.5 days (that was the gearbox, the driveshaft was less than an hour) It has all been found locally and at realistic prices too.
Don't underestimate the value of this site too. If you can't find it here ask any of the WA members and it will be attainable.
