Alpha one Gen 2 - Steering Pinion - Thread diameter

[alt]

Hi all,
We are attempting to remove steering pin on our Alpha One Gen2, there is a threaded slot to assist with pulling out.

Does anyone know the measurements of this slot?

It's the threaded slot on the left side of this pic.

Thanks all.

Can't remember exactly but can tell you its definitely not metric fairly sure its unc possibly 9/16" shouldnt be too hard to measure the hole & reference against a unc thread chart
