5L V8 Naturally Aspirated E7TE (225hp).
Quick reference
Verify coupe versus hatchback body style; part profiles differ significantly
Color codes (Black AAA, Gray BA, Scarlet TA, etc.) vary by interior trim code—base part number remains consistent but verify match
Early 1987 production (before 12/86 build date) may have minor clip positioning differences from 1988-1993
Context
The right C-pillar interior trim panel on 1987-1993 Fox Body Ford Mustangs (part number E7ZZ-6131398-A, later superseded by F1ZZ-6131398-A) covers the passenger-side sail panel and conceals the upper seatbelt retractor. This component fits all 5.0L V8 and 2.3L coupe (notchback) models from 1987 through 1993, but differs critically from hatchback variants due to roofline geometry. When sourcing from junkyards, inspect for broken mounting tabs—the plastic Christmas tree clip bosses commonly fracture from age and removal attempts. Check for sun warping and cracks around the seatbelt guide slot, as the belt passes through this panel. Installation requires rear seat removal and detaching the upper belt guide trim. Note that 1979-1986 Mustangs utilize different C-pillar architecture and are not interchangeable despite similar appearances.
