Getting fed up...

But... it wasn't a rebuild; it's a "new" unit that everybody seems to source from the same manufacturer, and yes, it's a crapshoot.
If I was forced to, I think I'd trust a rebuild more than a "new" (and incorrect) one- at least a rebuild is based on a factory casting. I don't know what's inside of a new one. But I'm gonna find out!
Amazingly, Autozone of all places used to sell American made and remanned starters, alternators, distributors, water pumps and other parts from a plant they had in Texas years ago. Of course, like other companies lookin to save a buck, now they outsource. It was a shame too, because it used to be quality stuff.
