So I was driving along yesterday, and noticed a NAPA store. I stopped and asked about a cable for my car. The guy looked and looked and looked and said "sorry we don't list one". I said try again, I was just one the NAPA site and there were two. He looked some more, got down the Belkamp book, and finally said "It lists one but its special order, from Beck Arnley."
Unfortunately I hadn't known I'd be going their, and hadn't bought the numbers I found on line that I posted here, so that was all I could learn.
It sure would be nice if you could find the number for yours - if you don't have any paper, you could call the store and ask them what they sold you, and win the gratitude of many on this list.
