Awesome! Pictures help a lot! And yes the back ones do have holes for screws, I assume they use the stainless screw with rubber on the back?

I got really luck on the trim - guy was selling a satellite on eBay with trim on and I asked about them, turned out he had a whole other set that don't appear to have been on a car. Only problem was no fasteners!

Another question, is the black insert painted, mine have some small scratches in the black but in other spot it almost looks like a thin black rubber or something?
