Headlight Adjustment
I really wish I'd asked this question a couple of weeks ago. I ment to, forgot and now I have a stone chip to pay for my procrastination 
My headlights won't completely close. They stay up approximately 1/8 inch. Just enough to stay in the airstream and get nicked. Can anyone tell me how to adjust the closure so they are flush with the rest of the bodywork?

You can open and close the headlamp doors manually using the **** next to the headlamp assembly. It may be that the doors are out of adjustment.
There can be a problem with stripped gears in the headlamp motor which would stop it closing fully. Theres a headlamp gear replacement part from Rodney Dickman which fixes that problem. If that was the snag I would have thought the door would be noisy when it closed.

Both lights stick up into the airstream. The driver's side is the worst offender. It sticks up 1/8 inch and of course it's the side that just took the stone ship. The passenger side sticks up 1/16 inch. Both headlites close perfectly and stop precisely in the positions I just mentioned.

The drivers side
Try this on the driver side. Take the headlight door assembly off and put 3 washers between the headlight motor and the frame. I would also check those plastic insulators on the metal tabs on the linkage frame on both sides of the car. Damage to these insulators could cause the headlights to stop in the wrong place. Usually when this occurs it is on the driver's side only and the door goes down and comes back up. There is a GM Tech alert out about the issue about the headlight going down and coming back up on the driver's side.
