I recently made a setup for my 82 Vanagon.  Several have mentioned about
removing the front bumper and that is what I did.  I think I have almost
mastered using a towbar on any type of Volkswagen so I put it all down
on a webpage.  Hopefully by viewing what I have done you can come up
with a good solution.  The website is:   http://www.vwtopia.com/towbar
