Spline count D80

[fifty]

Hey all,

Trying to order an ARB for my truck, its got the D80 in it, as she was originally a dually.

ARB and ford list 35 and 37 spline D80's for F350 for this year. Is there a way to find out with out sliding an axle shaft out or cracking the cover?

Does anyone know for sure what came on the cclb trucks in 02?

I thought stock was 35, and 37 is on the upgrade axles.

normally 35 in most fords but i would slide a shaft out. they did do some 37
