The 35 spline axles are way to big to fit through the standard stub axles.
Some pics that will put it in perspective.

I highly doubt you could use the stubs from ebay, you need correct diameter for both bearings, correct bearing spacing, it needs same bolt pattern, same length, and it has a lip that tightly fits over the end of the sals housing...
