Still have it.

I've seen that type housing with the plug on top, in fact I have one that has the flat spot on it to drill and tap a hole if needed. What I don't understand is what good it would do as its down stream of the thermostat. To be accurate shouldn't the probe be on the engine side of the stat?
Looking at your picture I'm wondering where the probe for your gauge or light sender is. Is it going to the plug on the manifold side of the head near the front? Is that the stock location for your year of truck? I had a machinist tell me that that wasn't a very good place for a temp sender due to being so close to the exhaust port. Any opinions on that?
Appreciate any help, thanks
