Complete 8-3/4″ 489 Case Rear End, Drum Brakes, and New Springs from ’73 Challenger


  • 8-3/4" 489 Case open differential with 2.76 gear ratio
  • Pinion Yoke
  • Carrier Mount Plate
  • Drum brakes and brake lines
  • The springs are new with no more than 100 miles on them. The spring pack came unpainted from the manufacturer so the surface rusted instantly.



Sorry, I’m still pricing out the parts while I try to confirm the part numbers, but I’m open to offers and questions to help me know what to look for. Located in California.
