Outside of used Vanagons, no one makes a custom molded carpet for the
Vanagon. Though you can put in a request (as I have) with <http://
www.stockinteriors.com> and hope that maybe they'll start doing one
(they do them for the older busses, just not our Vanagons.)

Hence, Sewfine is your next best choice. I really wish someone made
carpeting as good as the carpet in my Jaguar that I could install
into my Vanagon. Now that's nice stuff (wool.)
