The greenish grey bushing seems to have the bolt completely captured. The bolt that you see the threads of turns freely inside the bushing, the cone-shaped part on on side seems to be all one-peice with the threads and the "flange" (?) on the side with the threads. There are two "flats" on the small part of the flange near the threads that seem to allow for a wrench to be used but it does not seem to turn.
The linkage is from a 91 Stang, maybe I should post this in one of those forums. The problem is every time I ask a detailed question over there it gets ignored. They are real good at recommending which bolt-on to buy but I get the feeling that they do not spend that much time under their cars turning tools, and just pay some shop to do the work. Having spent 1.5 hours myself just to change out a set of spark plug wires I have to admit i understand WHY they do that...LOL. Did I mention I hate working on new cars?
