I got my old alternator off and waiting for my remanufactured Denso alternator from Amazon (

Or you can get a cheap one ($140) but worse quality at a local parts store.
Don't freak out about other people saying it is super difficult to do. Medium difficulty DIY IMO. And I'm no mechanic, just a garage and basic tools. Haven't installed the new one yet, but removing the old alternator was not too difficult.
The key is to remove the battery and the plastic platform the battery sits on, so you can access it from the top, not just bottom.
