New Type 3 fan shroud plugs fitting all Type 3 models from 1961 to 1973 that are running J-tubes (or disconnected heater boxes). This listing is for a pair of plugs.
Simply insert the plug(s) into the hole and twist the wing nut to expand the rubber ring while it tightens to the fan shroud opeing. These plugs seal the open ends of the fan shroud when you're not using the stock fresh air system. If these holes are left open, the air needed to cool the engine simply escapes and can lead to over-heating. Avoid using spray paint caps and go with these!
