I assume that you are talking about the "ears" that like to break off at the hole for the hinge pin. I brought my H16 to a local welder that could do aluminum. He built up the area with weld and I then used a disc grinder to reshape it to the original look. I then drilled the hole and it was good as new. Only cost me $15.00. I'm not sure the metal putty will take the strees.
