Yes Tim it is and the bracket I believe was spot welded to the upper spring frame. I thought maybe you could see it through the "flapper valve" hole in the bottom of the seat? Worst case is that it is not hard for an upholstery tech to remove the cover from the lower cushion and you could inspect or even make a bracket? It attaches and "unifies" the seat back and the upper plane of the lower seat cushion. I thought I took a million pictures of those seats in their "skeletal form" but the picture I showed earlier appears to be the only sighting of part of that bracket.
