And if you are going to the stores to check availability and pricing, see if you can find a store that carries AC Delco. I am not sure if they make for your car (I could check tomorrow if you like) but in many cases I have found the AC Delco cables to be a better price than the jobber ones, even though AC buys them from an outside source themself!
