The previous owner of my Fiesta St removed the rear seats, and now I'm trying to put them back in. When I bought the car he told me all the hardware was in the car, but there's definitely some missing parts. So far I've found that I need the left, center, and right hinge assemblies, but in the ford parts catalog there are versions with or without "load management" both of which say they fit the 2016 Fiesta St. Anyone know what the load management is? Should I save a couple bucks and go without it or is it worth the extra money. Thanks!
