Clear plastic plug, short

Clear plastic. 5/8"-18 threaded. OEM style replacement for OEM 704 (hex head) or 720 (Allen head) timing plugs. Designed to not touch the flywheel during dynamic timing. Note: For dynamic ignition timing with a strobe you may want to consider the much longer 925522 or 501865 clear plastic timing tool plugs, which are designed to just very lightly touch the flywheel to help prevent oil build-up on the plug for a clearer flywheel timing mark view.
