Allied Fiberglass / Astra (United States)

Allied Fiberglass Co. was an American automotive manufacturer based in Sacramento, California, active primarily from around 1965 to 1970. The company is best known for its production of fiberglass-bodied sports cars marketed under the Astra name. This venture began when Allied took over the production of Kellison coupes and roadsters, which were originally designed by the Kellison company.

The Astra lineup included several models tailored to fit various chassis sizes. The J-5 coupe was the largest, designed to accommodate full-size American chassis. The J-4 coupe was intended for medium-length frames, such as those of the Chevrolet Corvette, while the J-3 roadster was compatible with shorter European chassis, including those of the Volkswagen and MGA. Additionally, the J-2 coupe featured a distinctive double bubble top and was designed to fit on the Triumph TR3 chassis, among others.

One of the last models produced by Allied was the X-300GT, which was a modified version of the J-5 coupe featuring a raised roof for increased headroom. All Astra models could be equipped with special steel tube chassis that utilized suspension components from either Corvette or Plymouth vehicles. The company also offered a variety of configurations for headlights and headrests. In addition to the Astra line, Allied Fiberglass produced a dune buggy and a VW-based sports car kit known as the VW-GT 2+2, which bore similarities to the Fiberfab Aztec. The coupes were particularly popular, leading to significant sales during their production run.
