Does anyone in New Zealand know where I can get the gears of my 2002 WR426F undercut? I sent them to Boss Engineering Services in Wanganui, however they don't seem to have to necessary skills and/or equipment to do them properly so I got my money back. Are there any other places in NZ that will do them properly? I don't want to have to send them overseas or buy new gears. Any feedback appreciated.
