I'm not sure you'll be able to find it for less than the $390 you were quoted. I just checked with Autozone - they usually have very good pricing, but their price is $454.99 plus $150 core for $604.99 and that's a remanufactured alternator. Keep shopping and good luck - it's not going to be cheap! Let us know how things work out for you.
