It looks like you've got everything correct. I guess I don't understand exactly what the problem is.
It seems like the only thing that could make the stub shaft stick out too long is if the shaft is too long (it doesn't seem to be) or if the bushing is missing (or worn out). It looks like there is a bushing there, but I would start by looking there. It should have a shoulder on it. I sent you a link to the picture.
