I  stumbled upon a site that locates parts Vanagons  and other vehicles:
www.copartfinder.com

I am in no way associated with these folks nor have i used them in the past.
Just trying to be helpful.  What i am amazed at is the condition of some of
these Vanagons!!  Some look like they are in great shape???
