Extension Nr. I (2mm) needed

Hello,
, someone has the Smart Lock Ultra with the new universal cylinder 2.0 and can provide me with the extension no. I (2mm) to the inside if it is not needed. I need the extension 2x and Nuki and M&C are completely unable to supply me with this part. Instead I have to buy a complete new cylinder.

If someone does not need the component, has it spare and could make it available to me, I would be very grateful.

Best regards, Michael
