I see 17 people looked at my post but didn't answer. Maybe they were looking for the answer too. Well, I found it in another forum. Offset, (opposite of backspace) is the distance from the center of the spindle, a rim sits on a hub. In other words, if your front hub is 1/2" offset, then your rims/tires are 1/2"closer to the fender. A 1/2" backspace will closer to the frame. It has nothing to do with the way a hub fits on a spindle... I'm off to the junk yards to look for hubs.
