Those are not worth it in my opinion. I would fix it right, its not that hard. I have done a few and get the parts for around $200 I think. The newer replacement parts have been fixed so it does not happen again.
He can try the band aid fix, but I have a feeling he will be doing it again in a year or so.
Its really not as hard as people make it out to be. Just takes some time, about 4 hours last time I did it.
