While some *very* basic fasteners or small, generic rubber parts *might* be similar, you'll find no significant interchangeability for major components like:
* Engines: Completely different engine families.
* Transmissions: Different types and mounting points.
* Suspension: Completely different designs and configurations.
* Brakes: Different systems, calipers, rotors, etc.
* Body panels: Completely different shapes and sizes.
* Electrical systems: Different voltages, wiring harnesses, and computer systems.
* Interior: Entirely different designs and components.
In short, don't expect any significant part swapping between these two Mustangs. They're essentially different cars.
