Well Joe, I have heard cats passing hairballs (disgusting sounds), but never a starter motor that sounded like that. A unique starter you purchased. :D Back in the day when there weren't cheap "offshore" parts so readily available, we used to have starters, alternators, and generators rebuilt. Sometimes all they needed was a cleanup and a set of brushes, or maybe on open stator rewound, but it's almost always better and more reliable than the offshore junk. There are still a lot of shops around that do this, and it's probably what I would do unless I could find a genuine NOS unit for cheap.
