You'll be looking at a track increase of approx 1 3/4" (1.750) or 44.45 MM


Dr Diff (moparts member) makes a kit to retain your 70 Dart drum spindles and add the 4 1/2 " Bolt Circle center discs up front...might want to consider that option, unless you want the track increase for larger front tires?

If you want to stay with small bolt pattern then you can't use a 73 Dart setup because that is large bolt pattern.

Right, you have to use the 4-piston caliper and small bolt pattern rotor. wave
