Front Disk Brakes '73 Plymouth Duster 340

Now that there are options for drum spindles the Wilwood or Brembo/Viper option is on the table depending on what tie size you want to run. I run the Dr Diff 13" PBR kit, but that required a disc spindle. Cass is great.

As I understand 73-up Drum/Drum cars are still 5x4" bolt pattern? If so you'll need to address the rear and start to consider wheel offset and if you're going to run staggered wheels/tires or want the same size to rotate.
