MG MGA - Thermometer threads

Does anyone know (of course someone will!) the tap size for the thermometer bulb threads in the cylinder head (thermostat area) ? I need to clean it up. It's an early B head.

5/8 - 18 NF.

I believe it's 3/8 BSP.

David, you supplied that info a while ago!
Neil McGurk

Neil - Yes I did, but I later found out that it is in fact a NF thread (I even went down and checked on one of the jam nuts). Cheers - Dave
