Default Oil level sensor thread size?

I need to plug the hole for the oil level sensor. I went to the hardware store and bought a 1/2 plug but the sensor hole threads seem to be a real fine thread. any one know what size plug I need to use? I not to sure that it is even a 1/2 inch. I'm using a moroso pan and my long tubes are laying on the face where the wire conector goes.

I just left the sensor in there. No harm done.

I agree on that one wh buy a plug when you already have one.

The header tube is laying on it. It will melt that plastic inside.

I'd leave it, but that's me.

Although if I remember correctly, someone around here sells a plug for it....
