1969 Buick V6 225 "Odd Fire" stove pipe connection location Rochester 2bbl carburetor

I have a 1969 Glasply that I inherited that runs well while cold, but is hard to start when hot. After running through all of the electrical, I started on the fuel system. I discovered the stove pipe that controls my automatic choke isn't connected to anything.
This makes sense for my symptoms, but I can't find where this is supposed to connect. I've looked all over the intake manifold, and can't find any place where this should connect. I know I could convert to a manual choke, but I want to keep this running as designed.
Does anybody know where the stove pipe connects on the engine side for a 1969 Buick 225 Dauntless "Odd Fire" with a Rochester 2 barrel carburetor?
The attached images show the insulated pipe coming out of the carburetor and the cut off end that I can't find the engine connection location.

I would think on the exhaust manifold. Like on a car . As it gets warm it heats the air that causes the choke to open. Thats if the stove pipe goes to the choke. I cant tell from the pic. If it was vaccuum line it would be rubber. You had 2 kinds of chokes, heat and electric.

It should be just below the choke housing down on the manifold. It's a hole that the pipe slips into. You can make a new one out of brake line. Or a piece of the new style fuel line that has the flare about 1" above the end of the line.
