Doing a Red light 066 myself shortly- leaky crankcase gasket, not totally sure but I believe the 066 and 660 are the same. - easy enough to look up the part number.

The winged piston was older than the other both the same use wise

You can get a new OEM piston for about $40 if those pistons are showing a good amount of wear.

Weigh them and use the lighter one.

If it were me and I had my saw torn down that far, I would be VERY tempted to put in a new piston. And definitely new rings.

These piston/ rings still have plenty of life left in them. Until they deteriorate further i wont replace. Saw will be run occasionally not for daily duties.
