No, ours fit fine. They fit snugly onto the supplied shelf and require a little bit of squeezing between the poles, but they are not off by inches. Also, I don't see how you can easily cut them, as ours have a cover over them. Are you sure they are original to the X17Z or did the previous owner change them out?
