I got it from Mark at brillellicustoms.com. I paid for two machinings, for a great price. The stihl prop hub was custom cut with reverse threads. I sent him the crank to ensure a good hub. He also trued up a keyed flywheel center that I had. He even added the timing ring, though I did not need it. I feel like I robbed the poor guy, and the quality was great. Thanks Mark ![sm=thumbup.gif]
