wheel/tire size (71 dart swinger)

I have a 72 swinger, so the 15x7 with 4.25 bs should fit fine on my car correct? This is my first mopar build. I'm currently deployed and my wife bought a 72 dart swinger and trying to order wheels for it. I'm already tracking I'm gonna prolly have to do the 4in bolt pattern swap to the 4.5 in conversion.
