I'm in the middle of converting from the 10 spline to the full floater kit that Herm offers and am installing locking hubs. I flat tow my jeep and would rather not have to disconnect the driveshaft every time. Not that it is that difficult - just a luxury that will be a nice upgrade to my jeep. You'll have to go to the 19 spline axle and also replace the spyder gears in the diff. All the parts are interchangeable for either the Dana 41 or the 44.
