Most are 3.53/54:1 but you have to read the tag or better yet, pull the cover and count the teeth. You'll reuse your gears anyway, unless your wanting to change the ratio. In that case it doesn't matter. You're right about the spline count but that is on the outers. Mine has 35 spline at the locker.

first look at the front cover there should be a mall metal tag attached by a bolt...if theres not one lock the hubs, jack up one side, mark the pinion and housing in relation to each other, rotate tire one turn count pinion rotation multiply by 2...that'll get you close...then check availible gears ratios for your axle then you should be figuring it out...

If you pull the cover the ring gear will have the number of teeth scribed into it; i.e. a 4110 means 41 teeth on the ring gear and 10 on the pinion or a 4.10 ratio.
My Dana 60 front has 35 spline inner axles too for what it's worth.

Ford ID axle tag: Located under one of the bolts that retains the inspection cover to the housing...do not be surprised if it's missing.
Dana 60 ID axle tag:The 2" x 1/2" metal tag is bolted to the housing adjacent to the inspection cover to the left (rear axle) or right (front axle).
The tag has a 7 or 8 digit ID code, like this: 603010-1 or this: 603010-11.
The AXLE code is stamped on the Warranty Plate, but Ford usually did not list front dtiving axle codes.
