Thread size of oil temp probe

Hi guys,
I need to know the thread size of the oil temp probe in the sump, cant find it anywhere but need to buy the adapter for my new oil temp guage before i take it out if poss.

I tried to find this aswell but couldnt...

Could you not use the original sender position but use a T peice so both the aftermarket and OEM senders can still be used?

i could do but the oem oil temp sensor is useless as i dont have gti dials so have no oem oil temp guage. so thought it would be easier just to get an thread adapter as the aftermarket sender/probe/sensor (whatever its called) is much smaller than the oem one.
