I again have a bunch of those 4" Vanagon speakers that are black plastic
Blaupunkts.  These are the speakers that are stock in the '87 and later
Vanagons.  They are not the loudest, or the greatest speaker ever made but
they work and they are new and they are cheap ($6 each).  Let me know if
anyone would be interested in buying these.  You can retrofit them into 80-86
Vangons with no problem as the door hole is the same size.
