All I can say is, search for them using Suzuki in the wording but I'm sure those or similar that the link shows will fit or can be made to fit. (& may well be cheaper than Suzuki OEM ones too)
Then, when you find some that you can use, either silicone them into place or superglue them. When the top box sits on them for a while they stick to the underneath & pull out when you lift the top box off & fall off never to be seen again.
