I'm not exactly sure what bolt you're talking about that you can reach from the wheel well. I've taken off the alternator twice, which is held in by two main bolts and this little tiny other bolt that was missing from my car to begin with. I don't know if it's a lot different between Zetecs and Duratecs. I've got the 2.5L. The upper bracket bolt can be reached by sticking your hand down from the top of the engine where all the wiring and stuff is. Feel around for it and you'll find it . I am figuring you have a Zetec though cuz there aren't any bolts you can simply reach from the wheel well in the Duratec. Good luck with the rounded bolt.
