67 Dart Bolt pattern

Welcome! Assuming your front end was upgraded to 4 1/2" bolt pattern and the rear is the 4". Depends on what rear end your car has, if its an 8 3/4 (drop out center section like a 9"Ford) you can upgrade the axles, or have them redrilled. You can redrill the drums or upgrade the brakes from a B/E body. Theres lots of info out there on the internet.
