I bought an axle for the `61 Fury I am working on and made sure to get a NON Sure-Grip axle. So pulled mine out and compared to the replacement and believe they still sent me a SG axle because it is larger. It looks to be same length and bearing surface is same size, only seal surface is larger. I looked in book and bearing is same # just seal is different, so I ordered that to see if this will work.
I should know for sure if it will work when I set end play.
