Welcome. First, remove the seat and have a good look at things. There are brackets with welded on nuts on the back of the seat. And there are 2 bolts that go through holes in the toolbox and screw into the threaded brackets on the seat. Look at the bolts. Are the threads stripped or damaged? If so, throw them away. They are a common size, and you can get them at any hardware store, Home Depot, Lowes, etc. Now look at the threaded brackets on the seat. Are they still in place and tight? If so, and the only damage is the threads, The bolts are M6x20mm Get an M6 tap and see if you can clean the threads enough that new M6 bolts will screw into them. If the threads are too bad to save, they can be retapped to a larger size, or, if you can find another size bolt (maybe a 1/4") that can be forced to screw into the threaded brackets (if it is close, it will cut it's own threads) screw the bolts in a ways, then cut the heads off. Install the seat with the headless bolts sticking through the holes in the tool box, and put the proper size nuts on them.
I have the Kawasaki extended backrest, and run mine without any seat bolts on purpose. The reason is because if you open and close the tool box door too many times, it will break off. And the pad on the extended backrest holds the seat in place. But, I have bolt on saddlebags, and do not need to install them between the seat and frame. Installing many saddlebags like that will prevent the seat from fitting properly. The seat has rubber bumpers on the bottom which are designed to contact the frame. If you put anything between them and the frame, the seat will not fit down on the frame right.
I am a motorcyclist, NOT a biker.
