Quoted from Medisinyl:Good luck in the search.
For anyone unaware, a full set will be available to bid on at the Project Pinball charity auction during Expo in late October. It will be with the blue prototype building seen in the early video, and it will have updated wiring.
Once I make the "try me" box for the building, I'll post photos in this thread and in the auction thread here: https://pinside.com/pinball/forum/topic/project-pinball-auction-2021

I currently have 9 pipes on hand. Either color available.
Thanks again Greg! Your mods were great last time for the auction and we're excited to have these!
