I have a 2008 2-door.  seat works great except that it will not lock in position at the rear, so I put a bungee cord/strap from the seat to the d-rings near the tailgate to keep it from flopping up if I stop suddenly.  this is a good idea anyway, since if you fold the seat back forward, it unlatches by design.  There has to be a mod or hack out there for this since it's a common problem.
