I have just taken all of the old crappy mac tac off of the interior panels and put new vinyl on the panels.  I am however looking for the little counter sind washers for under the screws for when I re-install.  The originals have a backing to them so they do not rip the vinyl.  I can't find these anywhere.  Can anyone help with where to find these.  I went to vinyl dealers, car upholstry dudes and rv shops no luck.
