Here's the deal, I bought my truck a couple years ago and it came with an Autozone starter on it. The starter has started acting up and I want to get a new one. The Autozone starter is covered by a lifetime warranty. The catch is that they can't swap out my starter without tying it to a specific one that was sold. They told me it doesn't matter who bought one as long as they bought one they can use the info to exchange mine. They said it doesn't effect the other purchaser either since it can be swapped an infinite number of times under the warranty. So, if you have bought an Autozone starter (part # 17186) and don't mind letting me use your info to swap mine, let me know.
