I have a couple rusty hex head screws with a fine thread holding on my windshield trim the lower piece with 4 screw holes in it down by the wiper blades. Are these correct? If not what type of fastener goes there? Shouldn`t they be chrome plated or stainless steel to prevent rusting with maybe a Philips head instead of hex head? These don`t look like the right screws that belong there they look like those small screws that bolt the grill on. If anyone has a picture of this area showing the fasteners it would be appreciated!Thanks!
