Wheel backspacing?

[renny]

I plan on getting some black steel rockcrawler wheels and I want the front track to match the rear track. So would I need to get a 4 1/2 inch back spacing wheels for the front and 3 1/2 inch backspacing wheels for the rear?
My stock suspension 31x10.5R15 tired '85 K5 currently looks like there would be no tuck in room for the tires in the rear when the axle articulates upward and the other side downwards. /forums/images/graemlins/k5.gif

the rear is 3" shorter than the front so 4.5" for the front and 3" for the rear. spacers would be better because you can rotate the tires if needed.
