I recently purchased a set of used euro pistons from a member. He seemed pretty repeatable. But for my piece of mind how do you tell they are true 9:7:1 ? I checked the number inside the skirt but i see that number also showsfor the short skirt weight reduction pistons also. Any help or pics to compare will be a great help . Thanks
