I got it,
Its a bit uneasy to do but just pull . . . hard. Then it pops out.
LOL, thought I was going to brake it. But I realized it must be pulled after drilling and observing the clip and prying on the clip a bit. BTW, that metal is like butter to drill through, DAMN!
Oh, and the flattened shield helped right hand visibility alot, left hand glare and visiblilty were unaffected. And drivers dont have to worry about any glare issues (love the leveling motors!!)
