The pics that
@66fs posted are what I used. They are custom forged pistons from Race Tec. As of right now, there are only 3 sets of them in the world. My two sets and Dan's set.
I have the ring box with the part number at home. I'm at the beach right now, or I'd post a pic of the ring box. They were customs from Total Seal. If you decide to get some of the Race Tec pistons like ours, shoot me a PM after you order them and I will give you the part and order numbers for the rings.
