Got the 3rd set from here
3 x Sets of CF B-Pillars for Sale! but unfortunately UPS/FEDEX delivered them when the wife was at the front door. Then I got the 'you spent what, on what?!' so they are back for sale. I took them out of the wrapping, but never took them within 20ft of the car.
$130 shipped to CON USA, but will ship elsewhere.
