there are some drains at the ends of the cowl in between the cowl and the fender about four inches down from the top of the fender and at the front of the cowl.you cna get easier access to them with the fenders removed but may be able to dislodge the debris with an air blower and then rinse it back out but removing the fenders is the best way.the cowl itself may have some rust holes as the rain deflectors are about an inch and a half tall
