The problem is that those two parts may not be required for your vehicle. The Montana has a few options that would use rubber isolation mounts like those. The folks selling the radiator include those in the event you need them, but if the radiator is mounted good and is not loose at the top or bottom you should be okay and do not need them.
The issue with the manual is the same thing I have, they do not show every part used on every version.
They also could be the two parts on the top of the radiator supports marked here.
