I can tell you of the piston in the picture is what you are getting its not a Wiseco, its someone using the name to try and sell cheap junk. That's my suspicion anyway.
One thing i have learned from changing mine out is deal with Wiseco direct, its easier. I originally ordered my piston on amazon to save a few bucks and it ended up being a hassle. The piston i got was oversized at 67.75mm, amazon didnt have any left and it was a hassle returning it. I ended up buying one direct and the guy i talked to on the phone was helpful and made sure i got one that was indeed sized correctly.
