I got it connected with a little bit of help. It would be just my luck that I tweaked the tube!
Before I attached the ball housing, I did put the tranny in neutral and spin a tire to make sure everything was free. Everything turned freely with no strange noises. I ran out of time, but all that's left is to attach the transmission support to crossmember, torque the ball housing down, tighten the collar, and fill with oil.
Hope to get the test drive in today.
