    you dont have to keep the same cylinders matching. the cylinder numbers are stamped bore ranges for A-D size pistons. A's are slightly smaller & D's larger. Be careful purchasing used cylinders with out of round bores and or worn pistonon. The top crowns of the pistons have a habit of rolling up slightly. Most people dont even notice. I have what you need, but need to decide if I want to break the spare set I have laying around.

    At the top of the cylinder, if your looking down on it, right next to the powervalve opening. There is a number stamped 1-18.
