The parts you need are available through ORD for $200. It includes a new input gear with the short 32 spline input, bearing, and gasket and seal set. You will need to completely tear down your 205 to machine the case. The bearing that the input shaft rides in is larger, there fore that is the "hole" that needs to be machined. If you do it yourself, you need to make sure you don't move the centerline of the input. If you carry it to a local machine shop like I did, I would make sure to remind them not to change the centerline. The new bearing needs to be a tight slip fit into the new hole. It is a failry simple process because there are no retainig clip grooves or ridges to have to worry about, just a clean hole. Let me know if you have any more questions.
