However, there are some differences to watch out for:
* Exhaust manifolds/headers: These are often specific to the vehicle due to differences in chassis and body mounting points.
* Accessories: While the alternator, power steering pump, etc., might be the same *type*, the brackets and mounting points might vary slightly, requiring some adaptation or the use of Thunderbird-specific parts.
* Wiring harnesses: While the engine harnesses themselves are similar, there may be differences in connector types for sensors or accessories, especially if you have emissions controls.
* A/C components: These often have vehicle-specific brackets and lines.
* Transmission: While a 5.0L Mustang and Thunderbird may use the same transmission type (e.g., AOD), the bellhousing bolt patterns might differ slightly, necessitating the correct bellhousing for the specific application.
In short: While you can likely swap many 5.0L engine parts between a Mustang and Thunderbird, always double-check part numbers and compatibility to ensure a proper fit. Using a parts catalog specific to each vehicle (Mustang and Thunderbird) is highly recommended. Otherwise, you might find yourself needing adapters or making modifications.
