Right Door Vent/Fixed Glass - 1990 300ZX Z32

The right door vent glass on the Nissan Z32 300ZX is a tempered fixed quarter window distinct from the main drop glass. When sourcing used units, prioritize OEM 80310-30P10 (tinted) or 80310-30P00 (clear) from 1990-1996 coupe models only—critical distinction as the 2+2 variant uses longer doors with incompatible glass dimensions. Inspection at the junkyard requires checking the butyl rubber seal at the mounting perimeter for hardening or separation, common after 30+ years of heat cycling. Look for stress cracks originating from the two 10mm mounting bosses molded into the glass. Installation demands door panel removal and careful alignment of the glass into the stamped steel frame; the Z32's frameless door design means any misalignment causes wind noise at speed. If the casting shows 'AS1 DOT 177', you've found OEM-equivalent glass. Always test-fit before purchase, as mid-1994+ facelift cars may have different trim clip accommodations even if the glass itself interchanges.
