4 speed w/ 2 piece driveshaft, yes this is what I have. I have loosened the center part hanging from under the cab to have a little more play room. the rear of the driveshaft is disconnected from the rear axle. this is the part I cant get re-attached.I am thinking I shouldnt have to take the u joint apart, but cant figure out (as easy as it sounds ) to fit the yokes back together w/ the u joint in the way. i have slid the front of the driveshaft back into the rear of the trans, and bolted it up. I have not removed the spline part of the driveshaft from the shaft hanger at the back of the cab. the only place I am dis-connected is the very rear at the rear axle.
