    Modifying CMB Headers

    Hi Guys Thinking I need to change the angle of a CMB Header. The easiest way is to cut it and reweld it. Had anybody tried this? Sometimes the aluminum is too soft or has too many impurities for welding. Cheers Bob

    Colour Codes for late eighties Oberto Red & Green?

    Hi Guys Every photo I have of the 88/89 Oh boy Oberto makes the red and green look different shades.
