Any one know if it is possible to change the old Super Duty 10 Bolt dually type front rotors to the 8 bolt single rear wheel type with the old 6.5" bolt spacing? I have the a straight front axle from an old Super Duty telephone truck with the 10 bolt rims and I want to convert my o4 Super Duty 4 wheel drive to a 2 wheel drive. I need the 6.5" bolt spacing because I am replacing the rear 3.73 posie axle with a 3.07 axle from a 1990 Dodge 1 ton. If it is not possible to fit this straight axle with the 6.5" bolt spacing I will put the A frame front suspension from a 90 some dodge in it. I know it might sound crazy but I am working toward a 32 mile per gallon truck. Thanks.
