NOT A PRIMITIVE CRUISE CONTROL!!!! That's a very dangerous thing to do. What exactly the throttle cable was there for has been debated many times. True, earlier than about 1950 the carburetors didn't have a fast idle cam so you could use the throttle during warm up in cold weather and another guess that often pops up is that the throttle was used in the field with the trucks in low gear for one man hay baling.
I'm assuming that the long piece on the outside that you referred to is the fast idle link.
The bracket should be located on the engine side of the carburetor. The throttle cable comes down vertically the choke is the horizontal one.

The hole in the throttle link slides on the cable during normal operation. A very simple but half arsed setup but it worked for millions of vehicles for millions of miles for many decades, so it’s hard to argue with success.
