If you go to just about any hobby store lik eHobby Lobby or Michaels, they sell rolls of Levi's denim type material. They also sell new, and real, Levi Strauss buttons a auto upholstery shop can stitch on seats and door panels. The material AMC used on the Levis Gremlins, Hornets, Concords, AMXs & Jeeps was 'demin like material' same stuff sold in stores. In 1978 you could get not only blue but red, tan and black Levis interiors on your Concord, Gremlin & Concord AMX.
