I used an old drill bit that wasn't very sharp for a
punch to help locate the holes for drilling. After you
finish drilling the proper size hole then use a large bit like a 1/2" drill to just briefly touch both
sides of the metal. This will remove any burrs. You will need 6 x 16 MM allen
bolts to mount the new
bracket. I
got mine at Home Depot where they have all the specialty hardware. |
