Paul is right on asking the right person. There are a couple of ways to shrink metal. One is the way you mentioned using a small localized area heated and treated. The thing that is difficult is determining where to heat and where to tap the meatal. It is really easy to make things much worse really quick.
Another way is to use a shrinking disc. A good place to see what I mean is John's picture tutorial. http://allshops.org/cgi-bin/community/communityalbums.cgi?action=openalbum&albumid=9980121727059.
It can be done. It's not something I have mastered. I consider myself a rookie at that. Thankfully I haven't needed to do it yet on my JHs.
Maybe someone knows of a JH in a junkyard near you where you could cut out the whole piec and replace it.
