Wow, rwurst, nice simple write-up! You also have more patience than I and I'm a pretty patient guy. I would have told the guy to try to do at least some searching since this has been covered soooo many times and there a tech article on it.

You must replace the spark plug at the same time. To fail to do so is to risk damaging the new coil.
