I have a June 1974 Z and need a hood and right fender. I can aquire a Nov 1978 280 Z. Will the hood and right fender fit my Z? I was told the 78Z has a turbo head and a 5 speed. Is there anyway to find out if the differential is a limited slip rear end with out taking it apart? Will the differential fit the 74Z? Can I swap my 260Z head to the 280 motor to keep the carbs and use the 280z motor? Any thoughts will be helpful. Hawk
