Alternator Bolt Issue
My lower alternator bolt is seized up. I've put PB Blaster, WD40, and an industrial rust buster on it. Still no luck. I've bent a wrench and almost rounded the head of the bolt. I can still get a wrench on it, but if I put any more force to it, the bolt head will be completely screwed up.
Any tips for removing this bolt?

Thanks! I managed to get it out. Threads are rusted pretty badly. I had to use a prybar to force it as I turned the ratchet... Think a new bolt will go through?
Also, there's not much room to tap the threads... Ideas?
I thought maybe using a smaller diameter bolt, but I don't know if that would cause the pulley on the new alternator to wobble and wear out the shaft or bearing.

Get a tap (you have the bolt out, so measuring should be easy). Since you're just "chasing" threads, you can use a taper, plug, or bottoming tap. (Plug is most likely type you'll find at the hardware store.) Use oil; if there is damage to the threads (which is WHY you're chasing the threads) oil will help keep the tap cutting correctly.
