Ignition / 86s pin C4 automatic

[Acki]

Hey guys,

i have lost the pin of the ignition switch which switch the ignition / 86s on when the key is in.
Does somebody has maybe the dimensions of this pin or a source of a new one?

This pin only the C4 automatic is using. Manual transmission has not the extra pin - reason I don’t know.

Ignition switch removed - you can see the hole/bore in the middle?



This picture I got how the pin shall look like:


Thanks in advance for any help in regard of this topic :-)
