I know Camping World carries replacement vinyl and may have parts available. There is an Airstream Dealer in Colfax, NC (far side of Greensboro) that sells Faulkner as well as the Zip Dee Awnings. They are also Vintage Friendly to a point, and don't mind special orders.
....so many Airstreams....so little time...
