Any one know the size of the thread for the oil pressure relief valve cap?

I would like to use a mechanical oil temp gauge on an MPi block and the oil temp sensor hole is the same as the oil pressure relief valve hole.

If I am lucky I may be able to find an adapter, if not I will have to drill and tap an old cap to fit the sensor...

I drilled and tapped an old cap on my car. I'm sure the thread is on here if you search for the thread:

I searched as I thought it had been mentioned before. That pic has an arrow but no size for the OPR valve hole maybe I am not seeing the whole image.

From another forum I was told it is a non-standard thread, but it must be known as people make those variable spring rate adapters
