I have tried AGCO, NAPA, Hy Capacity, A&amp;I, Endurance Power, Clevite, Howard, Federal, Shortlines, Maibach Implement in Ohio, the machine shop that turned the crank down.  I can get .040 with a strait front bearing in a couple of weeks, but no single flange bearings.  The machine shop says he can probably make these work, but flanged sure would be nice.
