Need mounting rack for Kappa top case

So I bought this Kappa top case , K35 Monolock case and plate, but I can't find a mounting rack. Maybe I'm looking in the wrong places or just don't know what the hell I'm doing. Ie, what do they call the arms that attach to the bike on which the mounting plate is attached? that's a rack, isn't it?

I'm sure it's a simple solution but I just can't seem to find it.

Thanks, y'all

 

Doesn't Kappa fit the same plates that Givi does?
If thats the case then SW-motech got a nice mounting rack.

Finally figured it out.
Turns out the mounting plate that came with the case was designed for use on a scooter only. That's why I couldn't match up any side arms for my bike with that plate.
So, $140 for the right plate and sidearms plus $60 for the case and I'm be good to go. I guess that's still way cheaper than Givi and only a small sacrifice in quality.
