Ready to put my overdrive cable in. The t-handle will mount under the dash to the right of the column. What i need to know is how to route the cable. ie, through the firewall in one of the grommet holes then where and how many brakets to hold it. Also how does it connect to the transmission itself. There is a hole in the lever on the side of the tranny. How does it connect to the lever. I'm guessing a part is missing. I have the bracket on the solinoid but that is it.
