There isn't a Ford model that shares *all* the same parts as a Thunderbird, especially considering the Thunderbird spanned many generations with significant design and engineering changes over the decades. However, depending on the specific Thunderbird generation you're talking about, it shared many parts with other Ford models of its era.
To get a more precise answer, you'd need to specify which generation of Thunderbird you're interested in. For example, a 1960s Thunderbird might have shared some components with the Galaxie or Fairlane, while a 1990s Thunderbird might share parts with the Cougar or other Ford platforms of that time.
