You could possibly (carefully!) drill a hole where the broken off peg is and press a metal pin in its place. Either a dowel pin or a roll pin might work. I'm working on my second 46-420 during this past week. Luckily neither of them had the pegs broken off, but the clips holding the pointer bracket to the cabinet didn't want to budge. Had to finally add a drop of penatrating oil over each of them to get them to loosen up.
