I bought the 3L valves but not the locks/seals. Do I get the 3L locks and seals or will 2.5 ones work? I want to replace the springs also and I saw the ST220 spring part number. Is this spring required or just prefered when putting the 3L valves in? Anything else I need to order to make the 3L valves work?
