Jim:

I used the danielsternlighting page when I checked my
aim after installing new adjusters.  But I really didn't
need to re-aim.  Look in the archives for my post of
January 31st.  Just replace one adjuster at a time,
pre-setting each one to match the one you are about
to destroy by removing.  In fact, using pliers to just
crush the brittle plastic makes removing the old one
easy.
