Phil,
IF the pistons are original in a 40 year old engine, they would be
the 4-ring variety. The 5 ring were replacement pistons, the 5th ring being
below the wrist pin. But, order the 5 ring set as it has only the extra oil
rings, the other rings being the same between the sets.
It's a BIG IF, that everything is standard, though.
