Curious mind would like to know. What would it take to swap out an carrier assembly without the torque bar to one with the torque bar. I'm aware I would have to change transmission also. It is near impossible to find a transmission without the torque bar attachment. I bought a new tranny and had to put my old tail stock on and it till doesn't shift into 4th so I figured I'd try something else. Six speed exchange was once thought of but insanely expensive.
