Ford Mustang Bulkhead Replacement Parts

The sixth-generation Mustang (S550 platform) ran from 2015 to 2023, and bulkheads within that generation are the strongest starting point for a match. The fifth-generation (S197) covered 2005 to 2014, and its bulkhead is a completely different pressing to the S550. Always confirm the exact year and generation with the breaker against your registration before purchasing.

Both the 2015 and 2018 Mustang sit on the S550 platform, so they are within the same generation and a bulkhead from either year is a realistic candidate for interchange. The S550 did receive updates during its run, and whether any mid-generation pressing changes affect bulkhead compatibility is something you should confirm with the breaker against your registration. Do not assume fitment is guaranteed without that check.

The 2018 facelift updated the Mustang's front-end styling and various body panels, but the bulkhead sits behind the front clip and is part of the core S550 structure rather than a cosmetic pressing. Whether the facelift introduced any structural changes to the bulkhead itself is something to confirm with the breaker against your registration, as mid-generation pressing changes are not always publicly documented. The generation boundary to watch is S197 versus S550, which is a definite non-interchange.

Trim level and engine choice do not affect bulkhead fitment — the bulkhead is a structural body component tied to the platform and body style, not to what is under the bonnet. Whether you are replacing a bulkhead from an EcoBoost, GT, Mach 1, or Shelby GT500, the relevant factor is that all UK-sold sixth-generation Mustangs share the S550 fastback or convertible bodyshell. You may find cosmetic or bracket differences depending on what was bolted to the original car, but the core pressing should be the same within the same body style and generation.

The fastback and convertible are built on the same S550 platform but have different bodyshells, and the bulkhead — which forms part of the structural firewall and inner body — can differ between open and closed body styles. You should always specify your body style (fastback or convertible) when requesting a quote from a breaker, and confirm compatibility against your registration. Assuming the two are interchangeable based on platform alone is not sufficient for a structural component like a bulkhead.

No — the S197 (2005–2014) and S550 (2015–2023) are entirely different platforms with different bodyshell architecture, so their bulkheads are not interchangeable. This is a firm generation boundary, not a grey area. Always source a bulkhead from the correct generation for your car and confirm with the breaker against your registration.
