I was going through my between-the-front-seats console in Sweetpea and came across this two-page flyer for Euro-American RV Products (formerly Delta Six). It is a company based in Sevierville, TN that is an Original Equipment Manufacturer and Distributor of Volkswagen Bus and Vanagon/Westfalia Camper Parts.
There is a listing for curtain parts on this flyer (curtain hooks, glider, and shift lock). They also have plumbing parts, electrical parts, pop-top seals and canvas, rear mosquito screens, etc. You can go to their
future website, and discover absolutely nothing, or you can give them a call at (423) 908-9384.
