Haha. I used to have a 1997 Grand Am, and it had no front end links. The sway bar was there, but the links weren't. I owned it for at least a year before I realized. They were the simple thru-bolt with bushings supported by cup washers that GM used for awhile. Very cheap and easy to install. Can't say I really noticed a difference once I installed them though. The car was probably very floppy anyway.
I did also add a rear sway bar to my old 2007 Focus. Some came with them from the factory, some didn't. That did make a big difference.
