Does/did GM or Chrysler make alternators? Maybe a company under their corporate umbrella, but it certainly isn't a part that defines the car. Ditto for steering, brakes, suspension. Ever heard of Bendix, Moog, Raybestos? Just because a GM or Mopar guy picked a part from a catalog (often for low price), doesn't make it the part I must use. But then, I am not a MacHead either.
