I replaced my broken/cracked POS headlight adjusters with some long screws
i got at the local hardware store.  I made them adjustable by tightening 2
nuts against eachother on either side of where the threaded plastic piece
used to be.  Works great and i know its a hell of lot more durable than
the cheap plastic that is used all over my Vanagon!  Pmail for more info
if you need it.
