I actually already have the impeller, the same one you do.  It’s from a Mark 28 and it works if you file the keyway from what I’m told.  It actually fits pretty good just jammed over the square key, but I don’t know if it would tend to wallow itself out and eventually spin.  Going to fiddle with it a bit with some keys that we have in our stockpile and maybe custom file a key to fit instead of the other way around.
