Ditto what Gussie said. You can switch just the rails from one seat to the other. My driver side seat was starting to get worn so I switched them over with no issues. The only thing is that you will lose the tilt/slide function of the passenger seat as it has a small tab welded to the tilt mechanism that is triggered by a cable mounted on the slide mechanism on the passenger side. The driver's seat does not have the little tab.
