The parts that Pre'68 Dave is referring to are different three speed to 4 speed. But the parts will fit on the open style transmission. Find a bad 4 speed and rob the parts if you can. You might need to find the "ball and tube" from a 4 speed to match it all up. I think. Some one will know for sure. Does any one know if the torque tube is longer or shorter with the 3 speed? Seems to me the torque tube is the same but I have been wrong so many times I am used to it by now.
