One of the axle shafts is shorter than the other. You should be able to narrow the long side and put the shorter shaft in it. And narrow the short side of the housing the same amount you narrowed the long side, and now the long axle shaft will need to slide in far enough that the thicker portion of the shaft will be inside, and that can be resplined without having to get a whole new shaft made.
