My car was missing 3 of them, due to the prior owner's attempt at installing LEDs under the car. Idiot. I got them from a salvage yard. Look on
http://www.car-part.com" onclick="window.open(this.href);return false; for several Vibe parts (like doors, hood, motor, trans) to try and locate a yard close to you with a full car. Badvibe on here is parting out a couple of Vibes, might check with him. Or even email a few places with Vibe parts for sale on ebay. That would be more expensive, but probably less than a dealer.
