If your frame and fork are really JIS you can't use one. I thought of that as I was driving home. I can feel the difference with those bearings when the bike is on the workstand, but not when I'm riding it. I don't ride with no hands anymore. I'm too old, I have a family to support and I refuse to wear a helmet.
Whatever you get, don't use pliers on it. I've thrown away lots of parts that have been ruined by "mechanics" that have used pliers on them.
