[WOLFMANmike]

hey guys i got me some stainless door visors for my 65 c10 the kind that allow you to open your window a inch or 2 but deflect the rain anyway they came with no directions nada zip! can any of you that have them installed on your truck please explain to me how to put them on? and in some easy laymen terms please as im a bit slow on the uptake here. I would love your help thanks so much guys. P.S. they have 2 very small screws with them but i dont see where they would go on the door jam or window track im a bit lost here
