Rear Glass/Backlite - 1991 300ZX Z32

The 1991 Nissan 300ZX Z32 rear backlite is body-style specific: order 79700-30P00 for standard 2-seater models or 79700-30P10 for the extended 2+2 wheelbase. Interchange covers 1989-1996 production for both VG30DE and VG30DETT engines, as the glass is engine-agnostic but dimensionally distinct between chassis variants. When sourcing from salvage, prioritize inspection of the defroster grid busbar connections—corroded or snapped tabs render the heating element useless. Check the ceramic frit band for delamination, common in high-mileage T-top examples subject to chassis flex. Installation demands fresh polyurethane bedding and replacement of the reveal molding to prevent wind noise. The integrated third brake light requires new gaskets to avoid trunk leaks. Avoid convertible donor cars entirely, as they utilize a soft-top rear curtain rather than fixed glass. Always measure or verify part tags, as 2+2 glass exceeds 2-seater length by approximately 200mm.
