Hi Jim,
Sorry, if you followed the reference to a previous thread it took you to a busted link on my photo page. Here is a hopefully better one.
These are photos of the three places the headlight is held. I loosened the adjusters and let the thing swing open on the spring that is in the lower right hand of the photo. The next are close-ups of the adjusters and the spring. If you would like any more photos just ask.
