Coolant temp sender idea

[mattcrp1]

Hi all, I have been trying to figure a way to install my factory temp sender for the dash in my '76 with out being to intrusive. I tried to turn down a sender and cut threads into it and the sender was to thin. I don't want to drill and tap the head or the water pump, but I remembered that some ford products had a temp sender/switch in the heater hose like this one pictured. I figured I could cut the tube, flare the end and install it in line. Anyone have pro/con's about going this way?

Thanks,

Matt
