Funny thing,I contacted the guy just to find out where he got the bench seat.I had ordered one from joyner to replace the two rear buckets in my T4 but they never sent it.He told me the rear cage with the bench seat was custom made and fastens to the rear same as stock rear cage,on a hinge.He said he is willing to part with the cage and bench seat for 2,400.Cost him over 3k for the seat and custom cage.From what i understand it was for his kids,mentioned the bench seat had the high backs so his kids head would not whip back over the top of the seats as they would in a Rhino or Razr.
