Cheers, these are a set of over sized pistons for a 2H with the steel insert that you have mentioned. pic is a bit shiny but you can see the insert at the bottom of the middle ring gland. These are Hypatec Pistons in the pic. If you take your piston in to an engineering shop so they can measure it up for dia and height also need the rod connection size and rod connection position location in the piston then they can get you a forged piston that will be better quality than the Toyota piston. cheers gazza
