This is a 1961 - 1964 Cadillac power seat motor to transmission rubber coupler. This is the rubber piece that connects the power seat motor to the seat transmission. It was used for a number of years, so please make sure it matches yours before purchasing it. This has 2 different size inlets, and will not work on newer power seat transmissions that have a plastic / nylon shaft. This is a good used part, there is nothing wrong with it. Comes as shown, Sold As Is. Please let me know if you would like any other info. Thanks
