You would be better off getting an 8.8 Ford Explorer rear (98 and later had disc brakes), and were minimally wider than the 7.5/7.625.
Offset wheels can make up the difference and make it look just like stock in whatever you put it in.
Thanks M&M. I'm starting to think that width won't be a problem. I checked the ice race rules, and I'm allowed to flare the wheel wells 4" each side. So now I think all I need to do is source an axle that I can get an ARB locker in.
