How to find what spline axles i have

The front Dana 60 was easy but having trouble finding out what splines my rear Dana 70 4:10 rear has. Going to do a gear swap.

If in tech articles i have missed it.

IIRC the rule is bolts retaining the shaft ends 32, studs with washers and lock nuts 35 as they use a cone and washer design......

That's a big IIRC

32 spline took over in the dodge D70's from about '91.

About what I have found as well. My ‘91.0 has the stud set up and I have checked it is a 35 spline axle. The ‘90 Dana 70 i used under my Ramcharger swap is a 35 spline as well. It also has studs.
‘92 and up seem to all have the bolts style.
