I finally made it out on my 1976 D.S. II for the first time yesterday. It went pretty well. I think I finally figured out the boom vang. Not sure if I set it up right, but it seemed to work ok. I just tied it around the bottom of the mast with a short piece of line. Still uncertain about the centerboard rigging. Some pics i have seen show it attached to something from above in the cuddy. My boat doesnt seem to have anything this would attach to. Everything worked fine, although I didn't really have any control of raising or lowering the board.. Thanks for your help.
