Cowl side. When I adjusted mine I loosened the bolts just enough to be able to move them. I used a block of wood with a good pad on the end and placed that on the hinge and tapped real easy with a heavy hammer. There is probably a better way but that worked for me. I didn't want to loosen them so much that it moved on it's own. Maybe someone else has a better way and we can both learn something new!
