Original part #307522 or Sierra #18-2945. Later plastic style is #311598 or Sierra #18-4248-9 five pack. Should be able to get the Sierra parts at some NAPA Auto Parts stores? Orings won’t work except on the plugs that were designed to take them. They had a cavity designed into the plug to allow the oring to seal without being squished out.
