Up for sale is a N.O.S. Homelite Super 77 piston. My brother got this for his Super 77 as a backup in case the good used top end he'd gotten had a bad piston, but he didn't need it. He paid ~$85 for it from Chainsawr or Leon's, he'd like to get $40 + shipping for it. To the best of my knowledge it will fit all of the 5.8 C.I./95cc saws of that chassis as well, but you should check for yourself. It comes with a piston, rings, and pin, but I do not believe it has any circlips with it.
