Hi, looking for an early date (before 110) intake vacuum tree. Working if possible. Thanks

 

Thermal Vacuum Switch, in the intake coolant passage?

 

Yes...the valve with the 3 ports....i never knew what to call it. when i bougt the car years back it had a plug in its place but from what i understand all cars even my non air car came with one from the factory I have one in the manifold now but it has a 73 date on it i think
