I have a 2003 chassis and drivetrain but the front clip won't clear the steering. My plan was to cab swap it. The 2003 is a 1.5 ton chassis but was a cabover (like the isuzu cabover box truck) the leaf springs won't clear and the steering box won't clear. The steering box on the 2003 is 53 inches from back of engine to the front of the steering box. I think the 53 is only 20 something inches. The cab will go right on..... the front left fender will not.
