Any way of adjusting the Anko monitor arms to be taller?

I bought the dual monitor arms recently thinking they'd have some more adjustment in terms of height. The instructions aren't great at explaining what each adjustment point does, but as far as I can tell I have them set as high as possible. Has anyone found a way to get the arms to sit higher? I'm not opposed to messing with/altering them a little, they're past the return window so I'm a little stuck with them now lmao.
