1973 Dart Sport

You planning on cutting down the drivers side of the rear end axle tube or leaving it as is? I am considering the 8.8 for my next Dart project car and plan on cutting it down to match the passenger side plus I don't have quite the room as a Duster or Dart Sport

Leaving it stock length for sure. Not only will it save time and money, I really like the look. Really fills out the rear of the car. The original plan was to go with an 8 3/4 with 15x10s but the 8.8 with 15x8s should give me a similar look for a lot cheaper plus rear disks.
