The yesterday delivery is a new service, I need certain permission to make it happens 
For real, I tested them for the past weeks. Not as many kms I would like but the base plate is the same of the RKP and I am riding it for the past 800km. IF there is enough interest I can open a GB for the TKP adapter or complete.
I still have few RKP, then the Surf rodz TKP needs the upper part only. They are interchangeable. The cost would be the same of past GB
1 set includes 2 base plates + kingpins, nuts and bolts (fine for a board), it can be Raw or Matte Black .
Price 123.5 Euro (135$) + shipping . Based on the 1st GB 21 Euro shipping to US and from 6 to 20 Euro to EU. rest of the world depends where you are. Of course I can put them in bigger box and ship them together to US if someone is willing to help.
In case of the RKP or TKP adapter only (upper part), then I can do 66 Euro for a set (2 adapters).
