I believe that the backspacing on the stock rims is 4 1/2 inches. Most rims were about 7 inches wide.

On my 93, which has the 7.5-inch wide alloys, I believe I measured about 3.75 inches of backspacing (it's been a while since I did it) meaning that the wheel basically has zero offset. If you want to check yours for yourself, the truck's data plate in the driver's side door jamb will specify your wheel width, and you can pull a wheel off the truck to measure the backspacing. There are numerous websites that explain the relationship between wheel width, backspacing and offset - if you know any two of the measurements you can calculate the third - here's one: http://www.rsracing.com/tech-wheel.html
