okay,looks like a vanette,easiest way to tell is to lift the passenger seat up,there's a catch on the front,& it hinges backwards.under the seat there's a gold coloured sticker,this will tell you if it's an a12 or an a15.look for either a12s or a15s.if it's an a12,it'll have a 4.889:1 h165 diff,if it's a a15,it'll probably have a 4.11:1 h190.
