You have a bracket with two slots in it. My bracket is the same. The reason my bracket looks different is that I needed to make a slightly wider bracket to hold the 9mm belts I chose to replace my 6mm belts. I used my SO2 to cut a bracket modeled after the stock bracket. I had some Lumicite (acrylic embedded with fiberglass) in my stock, so I cut six brackets to replace all of my stock brackets.
I had noticed with my 6mm belts that they would flop around a bit, even when snugged up real good. Exploring other ways to route the belt, what I show locked the belt securely. With the routing shown in the instructions, there can be a variable amount of pressure keeping the ribs of the belt interlocked. With my routing, there is no slipping because the ribs are locked together well.
