Re: probe for water temp too long
289, that engine looks really nice and clean, congratulations.
On my 65 instead of an elbow there was a Tee that came out of the intake; one leg went to the heater hose and the other went to the carburetor spacer hose. I took off the hose to the spacer and tapped threads into the tee and put a temperature sensor in there.
So for those who are looking for a 3rd solution and you have a place to order 1965 parts, order the heater hose Tee and see if that will work for you.
