Scott, I think I have a solution for you, but you're going to have to settle for a shiny new Wiseco piston in a brand new box, with instructions and brand new rings, and it's going to cost you about $150 plus maybe 8 bucks shipping, about the same as any new Wiseco from a local shop.
Go above, click HOME, click SUPPLIERS, click BUEHNER SUPPLY. Voila, problem solved. Tell others. Good luck.
