Tried to remove my skid plate to access the engine oil drain plug. The plug isn't near an access hole but located between two holes. Can't get a wrench in to remove the plug. Short of drilling a new access hole (which I'm seriously considering), has any one been able to remove the skid plate? Seems to be a nut on the other end of the screw and there's no way I can access that nut. They must have bolted the skid plate on before putting the engine into the frame. Thanks in advance.
