Ok..... if no one has one I WILL be buying new (Wiseco for around $110)

Piston size 49.50mm to 51.50mm, 2 ring, 12mm pin.

I have no other "hard specs".

The reason I want a piston from the 1983 (or earlier) is because of the ring gap locating pins being spread far enough to clear my exhaust port on a Honda Lead scooter. I will be moving the jug (cylinder) to change the port timing a bit (spacing the jug up from the case to advance the engine timing) and planing the head to give me around 200psi.
