also, a little hard to see in those photos but there is a very slight ridge on the spines on the final drive too
from the worn splines on drive shaft.. should i replace final drive too?  or at least the input splines?

I view the rear drive splines as be severely worn and some of sawtooth tips ready to break off under load from a new drive shaft.
