Split Pin for gear selector arm - size?

[alt]

On the DP-E 290 drive, where the vertical arm goes into the gear selector, there is a washer and a split pin to secure the arm to the selector.

Has anyone any idea what size split pin is needed here? I forgot to order them from KeyPart so hoping to get locally, but no idea what size split pin will fit into the arm... as in I don't know what size hole is in the arm to accept split pin.

Luckily mine sits in garage, the pin measures 2 mm, its same dia as one that holds gear cable.
