I'd rather be eerie than creepy
My outer fuzzies had the clips (made into the strip) ... they have three prongs, the center prong goes inside the slots on the door, the outer prongs on the outside of the slots. They hold it down real nice when they snap in.
Yes the inners on mine go on with staples. Don't see why you couldn't screw on the fuzzies ... but you'd have to be real careful that the screw heads can't touch the glass and scratch it. Mine might need a screw in the back towards the door handle ... I don't guess they use a clip back there and it seems pretty loose ... although it's better when the glass is in helping hold it in place.
I'm waiting on some vinyl top trim so the window trim is still a week or so away. Thanks again.
