Front Right Window Regulator Assembly - 1991 300ZX Z32

The Nissan Z32 300ZX employs a cable-driven front right window regulator assembly, cataloged under primary OEM numbers 80730-30P00 for early production and the superseded service part 80730-CD00A. This unit fits all 1990-1996 USDM variants regardless of VG30DETT twin-turbo or naturally aspirated configuration, spanning both coupe and convertible body styles. When pulling from salvage yards, inspect the braided steel cables for fraying where they wrap around the brass drum pulley, and examine the white nylon guide rollers for UV-induced crystallization cracks—these are the primary failure modes after 30+ years. Installation requires drilling out four factory steel rivets securing the assembly to the door shell; replace with M8x20mm grade 8.8 bolts and nylock nuts to facilitate future service. Verify the 5-pin motor connector matches your harness, as early 1990-1992 models occasionally feature a different terminal arrangement than 1993-1996 units, though the regulator mechanism itself remains mechanically interchangeable.
