Ford Steering rack

Nope, that is the rack extension. I am guessing your track width is wider than the stock Mustang II 56.5" so they use those extensions to widen the rack by moving the inner tie rod further out.

Remember that if you decide to change the rack to something else. You will have to swap those pieces over to your new rack along with the longer boots.

Factory steering stops are the inner tie rod end bottoming out in the rack. You can adjust those with plastic clip on bushings to get less rack travel. They are a factory piece and still available from most of the mustang suppliers and were OE on the 93 Cobras
