There are 2 different diameters of Type 3 generators. IIRC, they are 
90 and 105 mm. If your current generator is the smaller diameter, you 
will need to replace your fan housing with a later one that has a 
saddle that has the proper radius for the later generator. I suppose 
it might be possible to remove your current fan housing and have a 
machine shop cut a larger radius. I don't know if there is enough 
meat there, but you should be able to inspect it and see. If you 
decide to do this, remember that it needs to be machined with the new 
radius and old radius on the same center.

Frankly, I'd expect that finding a later fan housing would be much 
easier than getting your old one modified, but I don't know how easy 
it is to find Type 3 salvage parts Down Under. I have several of 
those housings here, but shipping from the US would be prohibitive.
