What is needed to switch from sbp to 67 and later style wheels

Just as the title reads, I have a 66 barracuda and would like more wheel options. What is needed parts wise and how hard is the switch?

72 back is small bolt pattern so if you are just trying to go to 14" any A body wheel will work if the car hasn't been changed over. If you want to go to big bolt pattern then you need the parts off a 73 up disc brake car.
