    Default Will the swap work?

    I just got a line on 1981 GMC crew cab dually which is close and the right price. 454 engine. I believe it has the D60 up front and dually D70 rear axle. NP 205 case. Wondering if anyone has done a swap with these parts in their M715. I love to use the axles, power steering, etc on my M715. Engine has about 45,000 on it as well. Wondering if the axles will line up? Perches, driveline angles, hubs up front, etc. I'm already running a 460 with a C6 auto to my NP 200 as is.

    Thanks in advance.

    Chevy D60 fronts can be mounted SUA without much trouble. I don't know about SOA, but can't be that bad.

    The concern with the rear is the width, as the rear springs are very far apart and may hit the brake backing plates.

    Axle width (wheel mounting surface)... The front is about 74.5" IIRC, the rear I don't know.
