I spot NOS items on ebay regularly, though they are expensive. If you just want 'clear' headlights, perhaps use a headlight refurbishing kit, such as 3M's, which I used with clear topcoat, to make my headlights 'like new'. The last front passenger headlight was listed on ebay only a couple of weeks ago, so keep your eyes out for them. Do a search, and then keep it and get notifications when something gets listed. Then jump on it when you find one. That's how I got a 'new' emissions tray for under the back end.
