At one time there was a discussion on this. I thought that a couple of the later years of EB came with 31 spline axles. I did some checking and found that they only came with 28 spline axles. However.....the big bearing 28 spline axles are plenty strong. If your not going to use more than say a stroked 351W and 38's you should have no problem. Besides, the 28 spline axles are stock, cheap and easy to carry as a spare. They weak link in that semi-floater is at the bearing not the splined end and with a big bearing rear end its the same either way.

I read in my magazie that has the history of the Broncos that the 77 indeed did come with a 31 spline axles. Not to sure how you will find them but good luck. Ill even check that mag again and repost what it says.

As far as that notorious article, its been proven to be in error. Myself I sure thought the 76-77's came with them but nope.
As far as bearing size. You'll need to go to your local parts house. take a ruler. Have them show you a wheel bearing for any of the lower GVW EB's. Then get one for the higher GVW. Measure the race. I might have the measurements but in case I can't find them measuring yourself will have to do.
