Hy bluce, you have a 1965 truck, according to my Canadian parts book the 7000 lb. front axle fenders are the same from 1963 - 66, pns 3856108 right, and 3856107 left. These are not the widest fenders available, the 9000, 11000, 12000lb. axle fenders are wider. The cowl fenders (school bus fenders) have a different p/n, so they probably won't fit either, hope that helps.
