Unfortunately we don’t have any of the various clips/clamps for securing the overdrive cable. First of all, without the cable connected to the lockout lever, check it for smooth operation. If the inner and outer cable elements are corroded (or dry) try pulling them apart and cleaning any rust off......then grease the inner cable. If the cable seems badly corroded or badly kinked, I’d recommend replacing it with a new cable. We have those in stock.
There were several locations for supporting clamps, and you’ve seen some pictures in this topic thread. Over the years I think Ford tended to change the clamp locations as well. I have some drawings from several 49-59 chassis parts manuals that I have posted a links to.

The final clamp is shown on the solenoid upper bolt in one image and it’s on an upper shifter housing bolt in another image.
