Brake System light revisited
So that is a lower steering sector support from Firm Feel. Even with the steering box properly installed and tightened, the design of that box puts a lot of stress one the mount welded to the K-frame because the pitman arm is so far from the mount that it makes the whole steering sector shaft act as a big lever. Just get a friend to get in your car while you put your hand on the pitman arm at the box and have them reef back and forth on the steering wheel. You will be surprized how much play there is. You can improve that by welding stuff on the steering box mount on the k-frame, or you can secure the bottom of the steering sector to the k-frame at the bottom to eliminate almost all the play. The devise uses a long sleeve bolt in place of the pitman arm nut and that sleeve goes through a planetary bearing with the housing secured to the lower lip of the K-frame.
