This product is an NOS Part.
NOS items are OEM parts from Ford that have been sitting on shelves or in warehouses for years. These are often great examples of the orignal parts, but they may have scratches or other shelf wear.
However be aware that some NOS parts are "service replacement" parts. "Service replacement" parts are not exact replacements of the parts that were installed at the factory, but are what Ford considered as "good enough" and were used at Ford dealerships after the original supply of parts was exhausted.
We often leave NOS product listings on our website after they sell for reference purposes.
NOS FoMoCo part in the box. This is the rubber bellows also called the vacuum servo on many speed or cruise control units installed on many Ford products in the 1960's. Likely a component of the servo assembly as installed on 1967-69 Mercury Cougar and Ford Mustangs. Likely also could be used on 1965-71 Lincoln, Mercury or Ford cars with factory installed speed control option.Very hard part to find, the rubber deteriorates from the heat generated by the engines on these cars. Please check your application, this unit has threaded studs on both ends, and a single vacuum line as shown.
