Well the lifetime warranty is sweet, but I don't know about him finding the cure and not telling anyone. Why would you not tell anyone? Anyways, it can occur after any mount of time, the only thing that is for sure is that modding a 7 bolt (especially with a heavy clutch such as the 2600) will only expedite it. This doesn't mean that every 7 bolt will walk, but I say why take the risk? Anyways, it sounds like you should be all set, I just wouldn't recommend it to anyone else.
