Stillpoints Ultra SS adapter needed, help...


I just purchased 8 of the Stillpoints Ultra SS for my speakers.
My speakers are the Eggleston Works Andra II. They use a 3/8"-16 thread and the Stillpoints use a 1/4"-20 thread. Stillpoints can provide an adapter but only up to 5/8" long on the 3/8" side (speaker side) and the Andra II's looks to need about 1 1/2" long.

Do any of you know where I can purchase such an adapter or even what its called so I could search the internet?

EVO Ind came through. Adapter fits like a glove. Very fast professional service.
Question:
Does the hard hat on the Ultra SS go facing up or down when placed under Amps, Conditioner etc. ?
Well just an update:
I have read all of the great reviews of the Stillpoints products, but however, it seems they do not work wonders everywhere.
I tried a set of the 4 Ultra SS under my BSG QOL unit shortly after installing the other Stillpoints ultras sets under my speakers.

The music sounded dead, flat. Thinking that the Stillpoints changed the dynamics of my speaker placements, I started moving my speakers all around the room trying to find that lost magic.

Well, what I found was that it was not the Stillpoints under my speakers but the Stillpoints that were now under my BSG QOL unit that deadened the sound. The Synergistic cones that I had had underneath the BSG QOL unit were far superior to the Stillpoints (at least under that component). Once replaced with the Synergistic cones the dynamics and the air returned to the music.
