28 or 31 spline

With a f100, 3.25 gear open I would guess it's only going to be 28 spline.
Would that be correct??

99.9% of all half-ton bumpsides have 28-spline axles. I've heard of a couple having 32-spline, but they're so rare that they're not even worth the time looking for one.

You mean 31 spline.
Mine came stock with a 9 3/8" gear, limited slip, 31 spline diff in it. Lucky me.

Whoops...damn fat fingers...they don't always fit the keyboard! You're right, of course.
