New to A-Bodies

Well it was a no go on picking the car up tonight. I called the seller when I got home to make sure the tires were delivered, and they were, BUT..... He forgot until they were putting the tires on that it needed a part that he had, but hadn't installed yet. I couldn't quite understand him when he said what part is was. Something bar. Only thing that comes to mind is a sway bar. He said that they were installing it now and want to do a front end alignment before I drove it away. Normally I'd be a little upset but it seems this guy is being professional about the whole thing and am more than happy to hold off for a day if he is making sure that the car is in proper condition for me to drive home. It is supposed to be done by noon, but I wont be able to grab it until after work. So...... pictures tomorrow.
