Spindle Flaw Defect Yes or No

This a rear spindle from a 1981 corvette, disk brakes w/inner ebrake drum,10,000 miles original miles. We disassembled the rear end unit to replace the bushings and component cleanup.

You can see what looks like a casting flaw where the inner/inner race collar sets.

Is this acceptable?View attachment 1716571079

That almost looks like a Weld Repair with porosity. Take and have somebody weld it up and lathe it... or buy a new one.
