Just curious -did you perform the leak test before you got into this? Your cylinder doesn't look bad at all and the way you were posting about the bent control arm and grooved and sandblasted cylinder, I know I for one assumed we were looking at your current system. The NAA Piston only has one groove. The rubber O-Ring uses a leather or neoprene backup washer/wiper behind the O-Ring and I don't see one. O-Rings are for creating a seal. They don't 'center' anything and there's no 'rocking'. You may get by with a basic valve chamber cleaning, anew safety relief valve, and new piston. I have a new NAA Piston, with O-Ring, and backup washer I can let you have.
