Spindle deformation is caused by what?

Are those '70-72 E-body spindles? Because if they are, using the 73+ inner wheel bearing will do that. The bearing has a larger inner diameter so loading the bearing pushes the seal against the spindle and backing plate.

It was advertised as a 73. Confirmed the measurements for a 73 spindle. Has me at a loss as to what could chew a groove that deep. If it can't be seen, there is a deep lip on both sides.
