i may have one
i have a Bosch rebuilt in the garage, available if you want it. I can't recall the specifics, but i think the update was (the 459?) is a smaller diameter motor that requires an adapter (screen) plate.
Will try to run it over to You today so you can at least see. In the middle of heads gaskets on the 560, son wrenching while i blindly lead!! Hope to see you later this morning.
