Approximately 352 2 seater Z31 model 300ZX cars were converted during the 1980s by R. Straman Company. The total cost was an additional $8,000 on top of the price of the car. This “option” was available through a number of dealerships mostly located in California.
R.Straman Co. would convert any 2 seater, turbo or not. The tops would be cut off and most of the interior parts were retained. The frame was strengthened by adding additional runners as well as cross bracing. The trunk appears to be made of layers of fiberglass. The third brake light is added from a couple different sources to the 86-89 models. As the rear hatch as been removed, the turbo models lost their original spoilers.
