Did any GT's ever come with a rear seat??? I don't think so but thought I would ask. I have a family of four and am looking to put a rear seat in my GT. Any suggestions? I think there is enough room for my 2 small munchkins (3 and 6). I would have to take out the rear 'platform' and find a seat that would fit between the rear wheel wells and then of course attach seatbelts. Anybody do this before? Any suggestions before I begin combing junkyards and measuring all rear seats I come across?
