Fiberglass Fabricators was a manufacturer based in Tucson, Arizona, known for producing the Mark-1-41, a fiberglass-bodied kit car. The Mark-1-41 was styled to resemble a scaled-down version of the 1941 Lincoln Continental convertible. It was built on a full-length Volkswagen chassis, and buyers had the option of adding a hardtop. The car was offered both as a kit for home assembly and as a fully completed vehicle.
