Default Spline count front axle

What is the spline count on the axle shafts in the front axle

I have a locker in my old 2000 parts truck that is 31 spline idk if they changed them in these I know the 97-03 had 28 or 29 spine in the front

I looked on some websites trying to find replacement shaft to figure it out but all that kept coming up was cv axles

need to know year/model


front is a REVERSE cut 8.8 28 spline, and if you have a 5.4 engine, the rear is a 34 spline 9.75 Ford.

I'm not sure to be honest but part numbers would be an option wouldn't it? If you go to the parts desk at Ford they could answer that quickly
