They're all the same piston at this point. Some 266's dd have the full circle piston. Not sure it that was ever used on early 670's, but I suspect it was.

Later 670 piston, a Super or Champ is the same piston as the 268XP. Sifting through old IPL's can cause some confusion, as there were changes over the years. But ordering any 50mm piston for these saws will all supercede up to the same number, which is the 670/268XP item.

If you prefer the full skirt style, Forester has a really nice one that I've used a couple times. I don't have a strong preference either way, but that is the one 50mm open port AM piston that I have easiest access to, so that's what I've been using.
