Finally found a cheap correct solution to installing a temp sensor in the 5/8" heat exchanger hose.
You can buy this sensor at Ace Hardware for $3. I have since trashed the bag so don't have the size of the fitting. The large ends are for 5/8" hose.
Tap the small hose barb with a 1/8th pipe tap. Standard temp sensor will fit this tap perfect.
The great thing about this fitting is the sensor is just in the coolant flow and won't badly effect performance. I do have to tap the housing for a ground, but that's pretty simple also.
