The Ford Tractor hand cranks cannot be used if there is a grille guard/bumper attached the axle. There are two pins/tangs on the end that fit into the kingpin for a positive stop. The wartime model came with a special crank that was spring loaded (for kick back) and had a wooden spinner handle. The NAA version came with a forged knuckle on one end. *There is a How-To’s here to make your own but note that the diameter of the shank is listed as 5/8” however the original diameter of the cranks are 11/16” so don’t know how well they work.
