So why do you think that just that one pistons rings are bad?
IMO if you are going to do all that work for just one,
you might as well replace the others, while you are in there.
Plastic gauging the rods bearings, and mains, just to see how thier tolerances are.
The zone is the only one I know thats Free.
They should hav pics for the piston removal parts, try checking through thiers.
Thier are many online manuals that are better but cost some $$.
