Seems reasonable...do you have some pics of the axle end of the freehub?depending on the rear wheel you have there are two types of free hubs an American classic three pawl design or a shimano 8 xt level free-hub type... american classic uses two five mm allen wrenches in axle ends and woo hoo the show pulls apart easy as, careful with the pawls they may dislodge... you can tell externally what type of free hub mech you have as the american classic ones have a massive nut and shimano has pins.
