how would i get a hold of them?Talk to some of the guys who import JDM parts for the Rushworks. Places like Autofashion, JDM Palace, etc.
And unless you find someone selling a used set of Helix smoked tails, you aren't going to find them. Helix quit producing the smoked tail lights over a year ago. They only do the red/smoke combo now.
I may have a set of Helix smoked tails up for sale soon. It is up to the wife whether she wants to keep them or not.
