Chris it's hard to beat Autozone's warranty. Even if the part lasts only three years, it provides peace of mind knowing that one small part of the car now costs less to enjoy.
I offer my upper mounting bracket as an easy way to convert to Autozone's lifetime-guaranteed alternator, but it seems like most owners don't see the value. One example from an eBay buyer:
"I like your product but it is difficult to spend $50 on something that is not currently broke on a car I almost never drive."
Maybe we would drive these cars more often if more components were backed by a lifetime warranty? Catch-22!
I love your bracket. Makes replacing the Alternator THAT much easier. Also a better ground to the engine. Thanks for an awesome product!
