5L V8 Naturally Aspirated E7TE (225hp).
Quick reference
Verify donor vehicle is not a 1984-1986 SVO model; these used unique spindles for 5-lug hubs and different brake offset.
1979-1981 Fox Body spindles share similar silhouettes but use smaller 48mm inner wheel bearings; installing these with 1987 rotors will cause catastrophic bearing failure.
Mid-1993 production transitioned to SN95 platform components; verify Fox-specific casting marks (E7SC, E8SC, E9SC, F0SC, F1SC, F2SC) before purchase.
Context
For the 1987 Ford Mustang 5.0L Fox Body, the front left suspension knuckle (Ford OEM E7ZZ-3K185-A) serves as the critical hardpoint connecting the MacPherson strut, control arm, and wheel hub. Junkyard interchange spans 1982-1993 Mustang and 1979-1986 Capri Fox platforms, but strictly avoid 1979-1981 donor cars which utilized smaller 48mm bearing spindles incompatible with 1987 brake hardware. When inspecting a candidate casting marked E7SC-AA, check the spindle pin for seal scarring and the ball joint taper for egg-shaped wallowing—common failures include hairline cracks around the caliper bracket mounting ears from curb impacts. Installation requires a pickle fork separator (never hammer the casting directly) and torqueing the strut-to-knuckle bolts to 85-105 ft-lbs with the suspension loaded. Note that while the F2ZZ-3K185-A supercession fits perfectly, early ABS provision machining on 1990+ units may require plugging unused sensor holes on your 1987 application.
