For what it is worth I just picked up a 63' and one of my first projects is squaring away the TOTT. I have some photos from a guy named Jay of his tear down I can share. I have some pics of my basic adjustment attempt on my Flickr site. The three links below from another forum site and on a youtube video on a later model.
