15 x 7s, what size would you run on a 68 four door dart ?

if it's out of an XJ, it's 60.5" drum to drum. Everything I've seen, YJ and TJ wrangler axles are the same width (60.5"). I have an XJ one in my garage I was going to put in my duster, but it does limit tire size unless you go high offset wheels, so I'm looking at picking up a ranger 8.8, which is 58.5" wide.
I had to go look and remeasure to be sure- but my YJ is 58", wich is about a half inch narrower than the A body? Spring pads are identicle spot, only wrong side of the axle. Looks like I am going with the cooper 205s, so fitment should be pretty good.
