Stant's website has an extensive parts search. So if you go there and find your car/truck, I don't understand why you can't find a suitable cap. I needed a cover for my Ford Econoline V-10 petrol camper van that was not on the first list of Ford E-350 results. However, knowing the type of petrol + engine size and year of manufacture, the cap I ordered (10502) fitted perfectly as it was the same cap recommended for other gas models of my year (1997).
