2007 Forester resonator-rear cat flange

[dandydon]

Howdy. Just removed the muffler/resonator from our Forester and found a serious problem. The flange on the rear cat pipe (to resonator) is really disintegrated. I'm leary to put it all together because you generally have to really crank down the bolts, with springs, to prevent exhaust leak. Does anyone know about some kind of bolt on repair kit? What part #, where to find, etc.? Any help appreciated.
