    Might be a stupid question, but here goes....
    I have a mm2 plow setup with the 7.5 rd blade, would there be anything stopping me from swapping the blade to a 8 ft. hd blade. The truck is f-350.

    Thanks Ed

    You can check with a parts catalog, but I think you'll find the center pins to be different sizes (length and thickness).

    go to an 8.5 and clear those large f-350 mirrors. get rid of that 7.5. 8' and 8.5 are diff series of plow and strength. A lot is different if I recall, and I think the 8' HD series has another trip edge spring assembly.
