While some parts *might* be similar between the 2001 Ford Taurus and other Ford vehicles (especially other Ford sedans from the same era like the Ford Five Hundred, which it shares some platform elements with), it's highly unlikely you'd find a perfect door swap with another make entirely. Even within the Ford family, minor differences in door structure, wiring harnesses, window mechanisms, and lock systems would likely make a direct swap extremely difficult, if not impossible.
