Front Left Seat Belt Retractor - 1991 300ZX Z32

The Nissan Z32 300ZX front left seat belt retractor (OEM 86842-40P01) is a critical safety component spanning 1990-1996 USDM production. This assembly fits both VG30DE and VG30DETT variants interchangeably, though 1990-1991 early production may carry 86842-40P00 with distinct pretensioner electrical connectors. When junkyard hunting, verify the retractor mechanism isn't locked—pull the webbing fully and ensure smooth, spring-loaded retraction without clicking or binding. Inspect for deployed pretensioners (visible compression mark on the pyrotechnic cylinder) which render the unit permanently unsafe. Check casting date stamps (format: YY/MM) on the aluminum housing to verify production date against your vehicle. Installation requires 35 Nm torque on the lower B-pillar bolt and upper retractor mounting point, ensuring the webbing hangs straight without twists that cause premature wear. Note that JDM 1989-2000 Z32 units interchange mechanically but may lack USDM-specific seat belt warning lamp connectors or use different mounting bracket geometries. Always verify webbing color codes match your interior trim.
