It says on the website Amazing Auto LLC. "The only swivel that has ALL IN ONE design: with our universal design, this swivel not just fits both driver and passenger sides but it also fits multiple (make/model/year) vans with different parts that come with the swivel. (one swivel fit both driver side and passenger side all you need just flip it)."Those are for Sprinter, not PM. Pm seats and Sprinter seats are not the same.
