I just installed one of those Maple/maple replacement necks that you see on ebay from a shop called Magic Dragon. It had all of the holes pre drilled and it fit right onto my '99 MIM Jazz. In fact the fit into the heel pocket was so snug that I had to gently pound it in with the heel of my hand. It's in there much tighter than the factory neck was. The bolt holes lined up perfect. The tuner holes lined up perfect, but I drilled the little holes on the back of the head stock out a little so the screws wouldn't strip or break off. This new neck is pretty sporty. It has P bass dimensions and it sounds really nice. Snappy and bright and Maple like. A good deal for $85 including shipping.
