Hi Michael, I'm pleased to assist you. No, these are only for AWD. We have the cats for the FWD of the 2007 Ford Five Hundred. However, there are fit notes to be considered like the emission and where the vehicle is registered. Check the Vehicle Emission Control Information sticker, usually found underneath the hood. Federal emissions (46-state) stickers will simply say, "This vehicle conforms to U.S. EPA regulations," whereas California-emissions (50-state) vehicles will say, "This vehicle conforms to U.S. EPA and State of California regulations." Click on the link below (3 pages) to choose among the options we have available and order the correct one while supplies last. I hope this is helpful. Enjoy your online shopping at CP! https://www.carparts.com/search?q=catalytic_converter¤tpage=1&vehicle[model]=Five_Hundred&vehicle[make]=Ford&vehicle[year]=2007&can=CPGG4850_CSQA_20230307
