There is an interesting situation here. I have not yet heard of any shop offering to bore spindles out and install oversized bushings. However with the other problem with the axle, I think it is common to have the axle bored out and hardened steel inserts installed to bring it back to standard. I am guessing that repairing the spindles is a no no in the industry, maybe because of a lack of excess metal around the area of the spindle bores.
