You need to confirm if you have the original torque tube drive line or is it now open? It will affect as to how you move/lower the gear box. If it is a torque tube, disconnect and slide back the ball joint. Raise the ball joint end of the torque tube up pressing against the bottom side of the floor. Disconnect and lower the gear box to the ground. Now you have lots more room to raise and remove the motor.
I’ll take a picture of it because I don’t know how to tell!
