if you can get usa or jap bearings thats great , but if their made in mexico or china , buy two . they don't last . bearings are getting tough to find good ones . i'm in search of that tail stock bearing on the output shaft of the flange type 727 62-64 and its being a bear of a time , no one has good ones , and i was told by john cope transmissions that he saves the old one and just reuses them over and over . i hope you get a good one . save you the trouble of doing it again in your life time .
