Factory backspace for 14x5.5 rally?

Well the bold circle is 5x4.5." As for the width, I thought my original steelies were 4.5" wide, and the Rally's 5.5" or 6", depending on application. My set is definately 14" x 5.5" (measured them all, and mounted tires myself).

ahandful hit the nail on the head with the last sentance of his post, which I did not see until now (doing this at work, for shame). Although I'm getting these wheels cheap enough to be worth even a half inch extra space, I'd prefer an inch (roomy duster wells). And then there is the issue of trim rings to consider.....

I still think this is a cool idea. Both rims will be $90.00 shipped, and one of my rears is a little warped, so it makes even more sense from that perspective. Heading home now to walk dogs, and measure backspace....
