 The company also changed names again, to Howard Heerey Engineering Ltd. By 1972, Heerey had to close up shop and sold the jigs and moulds to HE Glass-Fibre of Hartlewood.They remained dormant until 1976 when KMB Autosports began manufacturing spare parts again, but no new cars were built until the parts and jigs were sold in April 1980 after a long period of negotiations.GTM Engineering (later GTM Cars) continued to build about 600 more Coupés in a number of iterations from 1980 until 1995, and updated the design in 1983.
