I don't know anything specific about that particular trunk, but let us know how you make out with mounting it.
You need the rear luggage rack to mount it on. The rear rack requires the sissybar to mount it. Otherwise, you will need to fabricate some sort of spacer. I have found that the rear rack is too short and too narrow to mount any trunk large enough to be worthwhile. Plus, the mounting systems tend to be cheap and ugly. I don't know that I'd want to "lean" on it...
Some fabrication may be required.
