I have been looking everywhere to purchase this and cannot find it anywhere. I have a 2003 Xterra but I believe any of the ones for xterra will work. If anyone has one for sale, or willing to part with it, I would really really appreciate it. I live in Chicago and needless to say, I've lost 2 spares to theft.

That was the site I found it at, but they seem to have disappeared.
