Hey mate, what body is it going onto? I recently had to do one to fit onto the HT TT. All i did was, by hand, with a fresh new drillbit, run a 3/16 size down into the head, then, an 8.5mm, then with the little orange stone wheel on the dremel, i wittled down the neck connector, around the edges, so it was just one straight line. Then just cut the end of, so it would fit into the neck, slide it in, checked it fit ok, then just glued the whole thing on. Worked a treat
