Nissan Fairlady/300ZX Z32 Door Window Lower Rear Bolt

Terra Firma Automotive provides genuine Nissan body and interior hardware that keeps your Z32’s doors operating smoothly and quietly. This door window lower rear bolt is the exact OEM fastener used to secure the window regulator mechanism inside the door panel. Engineered to Nissan’s original specifications with the correct thread pitch, length, and head design, it ensures the window glass tracks properly without binding, rattling, or misalignment during operation.

Many Z32 owners experience window issues such as slow movement, grinding noises, or the glass sitting crooked after years of use or previous repairs. These problems are frequently caused by missing, stripped, or corroded original bolts. This authentic replacement restores a solid mounting point for the regulator, allowing the window to move with the smooth, precise action Nissan originally designed. Its durable construction resists vibration and corrosion, maintaining reliable performance even in daily-driven or show-quality vehicles.

At Terra Firma Automotive, we specialize in supplying these often-overlooked genuine fasteners that are critical for proper door and window function. Whether you are repairing a malfunctioning window regulator, refreshing the door internals during a restoration, or addressing rattling issues on your 1989–1996 Fairlady Z or 1990–1996 300ZX, this lower rear bolt helps return the door mechanism to factory-correct operation.
