    mike are you talking about that ''gap''?

    Generally that kind of thing can change when it is a cast part, because engineers are always looking to make the casting and casting process more efficient. If it does not fit then it would be a problem, but i think that the replacement water pump manufacturer found a better way to make the casting, plus with continuous shapes they are much stronger than castings with pointed or sharp edges.
