Well I disconected everything wires and hoses.
The problem is that there is a protective plate that is welded to the frame and comes back under the front of the tank.
The back of the tank is flared back over the top of the rear end.
I tried to jack up the back of the tank and side the take back but it's to tight to do it. The side of he tank has a metal plate on it and is about 1 inch away from th drive line, plus even with the drive line removed I think the tank would hit the yoke from the rear end. So any tips from some one that has done this before. Thanks guys. Kurt
