 #1 Machine the thrower scroll off the crank leaving a bearing surface
with a diameter of 65mm. MINUS.000" PLUS .010"<

    I find it interesting that the diameter is in mm and the tolerance is in 
inches. As a designer something like that usually throws up a red flag and 
some phone calls. 
Good luck with the new engine this weekend at the track,
