Alright well ... I have looked around, got onto ebay, spoke to my old man and it seems i have to options...
1. Get one off ebay. Same plug hole and the mounting hole i guess you can call it? Looks like it could fit all mad. But I'm not sure on the brand :S (price $70)
2. The old man said there is a fee places round my area (mansfield) that sell altenators. A guy along creek road some where.. And another dude at stones corner. (Price 165 and up)
