Your post is a little confusing. You say that the racks are the PL360, then you show a photo with the V35 cases, implying that they go with the rack. If the racks are PL360, then showing the V35 cases is incorrect, because the V35 cases require the PLX360 rack.
All of this information is on Twisted Throttle's website and is quite clearly stated there. Perhaps you should clarify.
Further, both the PL360 and the PLX360 racks require either the Givi topcase rack, or a fitment kit that provides the same mount points that the topcase rack would provide.
