Go to the above http: link and figure out how to Zoom in/out by clicking on the area that has the 6 diagrams. Then zoom in on the bottom center diagram and the numbers seen there correspond to the descriptions of the components this parts company actually stock [colored in orange ]... thus the listing is NOT complete as to all such vacuum components.

Again... hope this helps. Let me know if I have correctly matched up your model number with your car.
