I just read the whole post, and i wanted to mention something. If your driveshaft ever fails instead of passing out booquoo bux for a new one, just get some 2 inch solid stock like you did for your hitch and make a 2 piece driveshaft. The t case connection on the larger piece and the Ujoint for the front diff on the smaller one, slide on inside the other and mount it up. The front shaft will most likely never be used fast enough to need balancing, and it will be strong enough to hold up to most abuse, given the welding is done right on the ends. I have a guy here in TN did it to his yoda on 37's and he says its an awesome setup. Cheap and durable.
