Adjusting wheel hub cones & lock nuts is an art. It's a fine line between perfect & too tight. Takes patience and a keen sense of feel. If you're trying to get some cones quickly order some off Amazon. Buy a variety of sizes & use the one that's the closest match. Shimano brand cones are good. But, they're usually a little thinner than other brands. You may need to get a few 1mm & 2mm axle spacers too.
