MC-1 black water/oil temp/press sensor/sender?

[auditude at cox.net]

On an MC-1 head from an '87 5kt automatic, there is a screw-in sensor below the water neck.  It has a black plastic section and terminates in a round post with a deep groove in the end, forming a "T" that a female spade connector attaches to perpendicularly.

Anyhow, that little tip is busted off so I need a new or different sensor.  Anyone got one or know what it is?

I was told it is for a gauge, but the online worldpac sites doesn't show a matching picture of the sensor, and the only listing without a pic is for a part that is said to be located in the oil pump, which this one isn't.

This head is going into my '88 5kcstq, which is coming back up after being down for a missing manifold stud (loud, the gasket had rotated around the remaining bottom stud, leaving it quite open), and then later during disassembly for three more broken studs.  It's all coming back together now, with just some final stuff left, such as the turbo oil and water line gaskets, screwing the heat shields into place, and buttoning up some plumbing and the airbox.  However, I imagine I need that sensor, and an engine mount I tore.

Thanks,

Ken
