What YC said but make sure you put it through the bottom link the opposite way to the stock bolt. The stock bolt threads into the stock shock absorber IIRC while the gsxr item you pinched from the top of the gsxr shock has a nut and bolt whihc can foul the linkage if you insert it the same way as the sv bolt.
You dont need the little ali bracket but you do need the bolt that holds it on
