Which threadsize to use for the vdo oil temp sensor?

[ditn]

Hello,

This friday i am going to buy some vdo meters for the ae86 and the sensors

=>oil temp gauge
=>water temp gauge
=>volt gauge

I found an interesting topic here on the forum thats says you can use
But there is a drain valve for the water, just 2cm toward the cabin,and there is a plug in the oilpump 2cm infront of the pressuresensor,that can be used for oil temp,it´s directly in the oilflow into the engine from the pickup.


Now there are alot of different sensors with thread that can be bought and i dont know which ones i need to get :s

sensors with different thread
