Anybody running Flextek arms with UE diffs? CVD's???

I'm trying to install a set of flextek arms on my brushless emaxx with UE diffs and cannot find a set of cvd's that will fit. These traxxas cvd's for the emaxx are too short

I also have a set of these MIP's and they are even shorter.

I cannot use the stock sliders with the UE diff cups and would prefer not change the diff outputs. When I stack the Flextek arms next to the stock arms, they are definitely longer by about 5mm.

I am thinking about trying these:

If anybody is running flextek arms with UE diffs, I could sure use some advice.

Thanks for your help.
