RARE 340 wedge car???

ya i'll try to post pics frm its restoration just got back frm pulling all the interior it already had one buildsheet excellant condition so i was pulling the front seats and i unscrewed the plastic backs hoping to find another buildsheet but no dice so on the passenger side i fliped it over to put the seat track screws back on it "so i know were there at later on" and there it was the 2nd buildsheet but only about half of it so now its a 1 1/2 buildsheet car
