Lots of people "list" parts that aren't there just to make a catalog look good. I have searched nationwide for .020" undersize conversion bearings three times in the past six months- - - - -they just don't exist! My friend who owns a very high-quality machine shop ended up regrinding a 216 crankshaft twice because one of his suppliers lied to him about having 20 under rod bearings in stock. After several weeks of delay they admitted they couldn't supply 20's so he had to go back and take another .010" off the crank to make it fit the only bearings they could ship. That happened in August 2014.
