I know this has been discussed before on this forum. If I remember correctly, 53-56 ford F-100 thru F-250 front fenders, inner fenders, grills and hoods are interchangeable. The F-350 had the bigger front fenders found on the larger trucks all the way up to the F-700, but the inner fenders, grill, and hood were all thee same as the smaller trucks. Does anyone know for sure if this is correct? Was the purpose of the larger fenders on the F-350 and up for tire clearance?
