Jason,
  I have an 85 GL that fell victim to the "Vanagon Syndrome" (bucking).  I
fixed mine with the Cap from Radio Shack and "knock on wood", our Van is
buckless since...  It is painfully obvious (especially if you work in the
electronics industry as I do) that you have to be PERFECT with the
modification otherwise you can wreck the AFM and see no resultant fix or
even, a worse condition than just bucking.  It is not hard to do but
precision is key.  I looked in the archives for the directions on the fix
and compared several postings from different times to make sure the
instructions were correct.  Good luck.
Rich and Annemarie
85 "GL "Buba"
98 Bug
