Getting ready to install a new piston in my Super sport. The piston is a Mondial 1966 which matches the old piston but I am not sure if it matters which way it goes in terms of top or bottom as there is no obvious mark? Please advise.
Thanks for the feedback... the only mark is a B but it is off to the side (not front or back). The valve reliefs are identical and by all my measures it is symmetrical so I am fairly confident at this point that it can go in either way.
