US/LHD Nissan 240SX S13/S14 Factory Front-Seat, Rail and Written-Contents Identification

US/LHD 1989-1994 Nissan 240SX S13 and 1995-1998 240SX S14 factory front-seat donors and separately identified rail/recliner components only. Prove both VINs/builds, S13 versus S14, body/production, left/driver versus right/passenger side, trim/color, cushion/back/frame, both rails and stops, recliner, release hardware, buckle/interface and written contents. Exclude imported/RHD Silvia assumptions, complete-seat interchange inferred from shared rail numbers, rear or racing seats, structural adapters and bent, welded, seized, crash-loaded or contaminated donors.

WHERE TO BUY

Open an exact listing, then confirm fitment, stock, price, and shipping with the seller before ordering.

Seller links checked . Prices and availability can change.

What you need to know

Start with both VINs/builds, US/LHD generation/body/production, seat side and trim. Photograph every label, full pan/back frame, cushion and upholstery, both rails and stops, recliner/release, headrest, buckle/connector and all mounting feet. Compare both rails as a pair and itemize shell/frame, cushion/back, upholstery, headrest, recliner, release hardware, both rails, buckle and hardware. Reject bent, cracked or welded frames, damaged floor feet, seized or uneven sliders, missing stops, stripped holes, serious corrosion, crash loading, cut wiring, fire/flood/mold/pest/smoke/biohazard contamination or unavailable actual photos. Qualified seat, belt and mounting inspection is required; no adapter fabrication or restraint bypass guidance.

OEM numbers

REPRESENTATIVE CHECKED COMPONENT IDENTITIES, NOT ONE S13/S14 COMPLETE-SEAT INTERCHANGE. S13 examples include right outer slide 87501-40F00, left outer slide 87551-40F00 with checked prior 87551-44F00, left inner slide 87552-35F01 and right inner slide 87502-35F01. S14 cushion assemblies split by side, production and trim: right examples 87300-70F20, 87300-80F10, 87300-81F00 and 87300-81F40left examples 87350-70F20, 87350-80F10, 87350-81F00 and 87350-81F40. Checked S14 recliner examples are 87451-70F00 left inner and 87401-70F00 right outer. Belts, buckles, upholstery, headrests and hardware remain separately verified contents.

Supersession

The checked S13 left outer slide record includes 87551-44F00 to 87551-40F00. Other listed values are production/trim/component branches, not a blanket chain. A shared rail or recliner identity does not prove complete S13/S14 seat, left/right, hatch/coupe or upholstery interchange.

Fitment

Start with both VINs/builds, US/LHD generation/body/production, seat side and trim. Photograph every label, full pan/back frame, cushion and upholstery, both rails and stops, recliner/release, headrest, buckle/connector and all mounting feet. Compare both rails as a pair and itemize shell/frame, cushion/back, upholstery, headrest, recliner, release hardware, both rails, buckle and hardware. Reject bent, cracked or welded frames, damaged floor feet, seized or uneven sliders, missing stops, stripped holes, serious corrosion, crash loading, cut wiring, fire/flood/mold/pest/smoke/biohazard contamination or unavailable actual photos. Qualified seat, belt and mounting inspection is required; no adapter fabrication or restraint bypass guidance.

Aftermarket options

Exact-frame upholstery or foam repair can be compared only when generation, side, production, trim and buckle/rail interfaces are proven. The checked cover seller is an upholstery alternative, not evidence of an included factory seat. Racing seats, universal rails, side mounts, welded or drilled adapters and imported RHD assumptions are outside this factory donor-identification claim.

Before you buy

Do not infer complete-seat interchange from a shared rail or generic S13/S14 listing. Match both VINs/builds, generation/body/production, side, trim, both rails, recliner, buckle/interface, actual photos and written contents. Imported/RHD and racing-seat paths are excluded.
