1970 duster with seized bearing on spindle - revisited
If it was me I'd replace the spindle as the threads look stripped out... That's a lot more concerning than simply using crocus cloth or filing away bearing seat damage.
Apologies - this is the correct pic where the damage can be seen. I have a new bearing coming this week and will do a test fit but still wanted to solicit your thoughts about whether I need to find a new spindle too.
