Will watch with interest, I am unaware of any place up here that specialises in this field, all inquiries I have made would indicate Brisbane being the closest reliable supplier. Are you talking fitting it yourself or having someone fit.
The only place I can suggest to start would be to call Chapmans Auto Repairs at Cooroy, I have had dealings with them and they impressed me (they have dynoed my Troll twice) and they seem quite knowledgeable.
I would have to get it fitted by someone as I work away and have no time when I'm home and I don't know to much about fitting that sort of stuff where would be a good place in brissy? If I have to go that far I will cheers guys
