CVD length with T/E Maxx Flextek arms?

I tried to install a set of flextek arms that I recently purchased and the traxxas cvd's are too short. I can't use the sliders because I'm running UE diffs and big bore shocks.

I need them about 5mm longer. Anybody know what might work? I also have a set of MIP's and they are even shorter than the traxxas cvd's.

I would rather find longer cvd's instead of changing the cups on my diffs.
