No problem, Mario. On a little side note, the Futaba alum. horn you bought has to be drilled out for the screws you plan to use. I usually use 3mm screws, so I just drill and tap the existing starter holes, and then loc-tite the screws into the horn. I don't like using nuts, although that will work fine too, with a through hole. In high stress applications, I've done both methods combined - drilled and tapped the hole, used a slightly longer screw, and then ran a nut up the back side of the threads, which protrudes the arm, like a jam nut. Nyloc nuts work perfect for this.
