Acclaim wheels on an A-body?

I tried some 14x6 alloy wheels from my 93 ranger on the duster and they were ok on the back but were dragging on the calipers, I guess the aluminum has to be thicker than the stock steel ones. not to mention that they were 14's. they also had about 3.5 BS. I wouldn't want to try to "walk" the holes on an alloy wheel, even I think thats unsafe and I've done some stupid things. :)
