I wanted to put my cowl back on my STR because it is pouring here. My passenger wiper arm is tight and fine, but when I put the driver's side on it sits flush against the windsheild, but when I go to tighten it, it sticks up off the windsheild. Any Ideas? I've tried moving it around for 45 minutes and each time I tighten it down, it sticks up. Thanks Again in Advance
