OZ 250 Coolant Temperature Sensor

[ozconv]

I need to get a coolant temperature sensor for my OZ 250 head before I install it, however, the hole at the back of the head appears to be a bit smaller than that in a 67 US head. Has anyone else had to deal with this and if so can you tell me what sensor you used.

The OZ head, and our aluminum head, use a 1/8" NPT Water Temp Sending Unit. You should be able to purchase one at any parts store.
