Chris,
I bought a kit which included the stering box, a new pitman arm, drag link, mount bracket, universal joint, & hardware for the conversion on my 56. If you send me an email I can send you a picture of the set up in my truck and the installation instructions (for a TF truck). I haven't figured how to post to this forum.
