Looks to be 10 spline hubs.

Pre 1950 Jeeps have a longer axle shaft end (nib) than later models, so even though 10 spline, they may not fit. I can’t see how this set of hubs could fit 1940’s through 1971.
thats right , you have to cut the threaded end of the axle off , who wants to do that ?
Neal,
Thanks for confirming this little known fact. Contrary to popular opinion, I DO KNOW what I’m talking about.
