Does anyone know the dimensions of the middle seat and how longn the rear seat is? I have spares in my attic at home and someone wants me to ship them but I am lazy and dont want to pull them down unless I am for sure the guy will pay the shipping costs. Also do you know how much theses items wiegh? They are a folding rear bench and a stationary 3/4 middle seat. I was going to strap them to a pallet maybe not sure. Any suggestions?
