You could either go to a Ford truck parts web site or to a Ford truck dealer, or any good auto parts store and give them your vehicle info and ask for what you want. (serpentine belt) Then see what they bring you. As others have said, you probably don't have a V-10, more likely a 460 (7.3 L) V-8. Or just look under the doghouse at the front of the engine.
A Ford Truck dealer may not be able to help you because of the age of your vehicle.
www.autohausaz.com Use 1994 Ford F350 with 7.3 L gas V-8 A place to start. You may also need a belt tensioner and idler pulley. Verify the length of the belt before you order. There are several different sizes.
