Are all the GS torque arms the same lenght

[Baldy Biker]

I was thinking of changing my torque arm on the 1100s, every one says change it for a GS one. But are they all the same size seeing that there has been several changes to that model over the years.
I have found some secondhand but want to make sure I get the right one.

the GS torque arm is shorter and meant to make the steering quicker. I believe they were shorter as standard on the boxercip replicas.
