Just bought a 2003 4WD HO Sport Blk w/Laramie Pkg. What I need to know is the bolt pattern of the wheel. I know the tires are 17" w/8 lugs but when I called DC they only knew last years pattern. I am putting the Centramatic Wheel Balancers on and I have to know the size of the bolt pattern(5. 5 or 6. 5?). Anything you can offer will be appreciated.
