As I know so far, VashDStampede is working on these ear decals (the inverted "U"'s for both sides), but that's a matter of time, cause probably he's working on the Jet Pack decals first, to then to work on the helmet ones afterwards.
We have no updates as of now about these from him, cause I was helping him out a while ago, and that's the last he said about it. Let's see in the near future what happens, or you could PM him for details.
