Splines count on FF axles

[ob0ne]

Hi, I have found a pair of differentials. They are drum braked and the rear is the full floater version.

What axle shafts count could I find in these? 30 only or some may have coarse splines?

Thanks! I don't know these but having a FF diff seems to be a good upgrade.

AFAIK, all FF for 40 series up to '84 are same as fine spline semi floater axles for diameter and spline count.
