Dude, you've really gotta calm down and start using proper punctuation. You have no idea how annoying that is on the internet.
As for $300 for an alternator, wow. You can buy a brand new unit from a guy on the Corral.net for $150 shipped, and it's a factory new Motorcraft unit. Rebuilders charge no more than $150 locally, and the last one I had done only cost me $100.
