I have two sets of fenders that are wider than stock, easily fit modern FWD front axle. Have large wheel cutout unlike stock 1.5 ton, narrow fenders. One came off school bus in mountains, other came off ‘42, not sure of tonnage ID. Sure make nice not to have front tires sling mud all over. I ton hood fits.
