I was looking at these wheels and i was wondering if they would fit a 2003 ranger xlt 6ft stepsise bed 2 wheel drive. I saw them on another site and they said the backspace was too much, is it? & also is the center cap hole large enough to fit? I have found the front caps tend to be a problem when buying wheels.
