I had a buddy from our field make it for me who is also a gunsmith. I plan on buying a metal lathe and a milling machine for in my shop here in the next couple of weeks to start making my own and for others into this converting gig (I used to use a lathe quite a bit). I also plan on making "stand offs" and custom mufflers. I will be making an adjustable collar when I make my own. Permanently mounted the magnets isnt bad as long as you get the timing right which isnt hard.

If you cant get someone to get you one made,let me know and we'll see what we can do. If you'd be willing to wait a couple weeks,then it would really be no problem,because I plan on making them myself. Keep in mind,its hard to do without having your engines bottom end(block and crankshaft at least) to fit it properly. So you might be looking at some shipping and time costs too. It would probably cost you $20 + any shipping. But yeah,let me know how you make out trying to find someone to get you one made sooner if your in a hurry.
