That's about all I can help you with. It looks like three different racks. 4 Seasons, MultiSport and Clamp on. With their related accessaries. No illustrations just text part number listings. But it may be enough to get you started searching the Internet for info.
Each Kit has a hardware listing but that's simply too much to list here.
