I'd be interested in seeing that article. Still, even if the car had been designed as FWD the change to rear drive would probably have been cheaper then scrapping the whole design. In the 70's the rear suspension would have probably been designed as a live axle anyway to keep costs down. My favorite Pacer was the one HotRod or Carcraft built with a 401 in it. All I can remember is they painted it white and IIRC blanked out the quarter windows to make it a Ute. That last mod would have killed half the appeal of the Pacer as the good viewing area was one of its selling points. Shame it couldn't have been intro'd during the musclecar era. A Plain Jane, stripper Pacer with a 401, 4 speed would be just plain cool!
